the manager of a restaurant in a large city claims that waiters working in all restaurants in his city earn an average of $157 or more in tips per week. a random sample of 27 waiters selected from restaurants of this city yielded a mean of $147 in tips per week with a standard deviation of $29 (sample standard deviaiton). assume that the weekly tips for all waiters in this city have a normal distribution. using a 2.5% significance level, can you conclude that the manager's claim is false? use the critical-value approach. round your observed value to two decimal places. observed value or test statistic of t =

Answers

Answer 1

observed value or test statistic of t = 0.05


As per the given data.

sample mean=147

sample standard deviation=29

sample size=27

a) Null and alternate Hypothesis,

mean≥157

mean<157

test statistic t=(147-157)/(29/sqrt27)

                    = -1.7917766

t-critical [ use excel function T.INV.2T (0.05,26)]

p-value=0.0424(from t table for p value)

range=0.01<p value<0.05

since p value is less than level of significance 0.05, we reject the null hypothesis.

Conclusion:

The manager's claim is false.

The type 1 error would occur if the mean waiters earning from tips was grater or equal to $157 but we concluded that it was (greater than or equal to) less than $157.

Wayfair Co. Reported the following results from the sale of 5,500 tables in May: sales $300,000, variable costs $165,000, fixed costs $85,000, and net income $50,000. Assume that Wayfair increases the selling price of tables by 10% on June 1. How much sales are needed by Wayfair to break even?.

Answers

Wayfair Co's sales needed to break even are 2,833 tables and $170,000.

Data and Calculations:

Number of tables sold in May = 5,500

Sales revenue in May = $300,000

Fixed costs = $85,000

Net income = $50,000

Selling price per table in May = $54.55 ($300,000/5,500)

Total variable costs  = $165,000

Variable cost per unit = $30.00 ($165,000/5,500)

New selling price per table in June = $60 ($54.55 x 1.1)

Contribution margin per table = $30 ($60 - $30)

Contribution margin ratio = 50%  ($30/$60 x 100)

Break-even Sales (Units) = Fixed Costs/Contribution Margin

= 2,833 ($85,000/$30) tables

Break-even Sales ($) = $170,000 ($85,000/50%)

Thus, the sales needed to break even are 2,833 tables and $170,000.

a. ignore
b. hide
c. become aware of
d. eliminate
e. expand

Answers

The purpose of diversity training is to help employees become aware of their biases.
Option c) "become aware of" is the correct answer. Diversity training aims to educate employees about various aspects of diversity, including race, ethnicity, gender, age, religion, sexual orientation, and more.

By providing education and awareness, diversity training helps individuals recognize and understand their own biases, stereotypes, and prejudices that they may hold unconsciously. It encourages employees to examine their beliefs and attitudes and fosters an inclusive and respectful work environment.
Options a) "ignore" and b) "hide" are not accurate because diversity training aims to address biases rather than ignore or hide them. Option d) "eliminate" is partially correct, as the goal is to minimize and mitigate biases, but complete elimination may not be entirely feasible. Option e) "expand" is not applicable as it does not capture the purpose of diversity training related to biases.
Therefore, the most appropriate answer is c) become aware of.

Which kind of transfer might be appropriate if there is a backlog if incoming calls in the queue?A. Hot TransferB. Quick TransferC. Cold TransferD. Warm Transfer...

Answers

If there is a backlog of incoming calls in the queue, a quick transfer may be the most appropriate transfer method. This allows the caller to be transferred to the appropriate agent or department without delay, which can help reduce the wait time and clear the backlog in the queue.

A hot transfer may also be appropriate in some cases, but it involves transferring the caller directly to a live agent without first placing them in the queue, which may not be feasible if there is a large backlog. Cold and warm transfers are typically not appropriate in situations where there is a backlog, as they involve placing the caller on hold or transferring them to a voicemail system, which can further increase the wait time.


An appropriate transfer for a situation with a backlog of incoming calls in the queue would be a Warm Transfer (D). This allows for a brief consultation between the transferring agent and the receiving agent, ensuring a smooth handoff and maintaining efficiency in handling the high volume of calls.

Answer:"As more Americans hold on to older vehicles longer, oil and tire change service shops see boom in profits."

"Influencers claim orange juice cured their insomnia; claim leaves doctors scratching their heads and store cases looking bare."

Explanation:

Final answer:

The demand for orange juice rises due to influencers' claims, leading to an increase in price and quantity demanded in the market. On the other hand, the supply of semiconductor chips decreases due to a shortage, leading to a rise in price and a decrease in quantity supplied in the market.

Explanation:

For the demand side, let's consider the headline: 'Influencers claim orange juice cured their insomnia; claim leaves doctors scratching their heads and store cases looking bare.' This suggests a rise in the popularity of orange juice due to the influencers' claim. We expect this to increase the demand for orange juice. In the demand graph titled 'Market for Orange Juice', the demand curve shifts to the right from D to D1, indicating an increase in demand. The new equilibrium price (P1) and quantity (Q1) are higher than the initial equilibrium price (Pe) and quantity (Qe). This is an example of a change due to TRIBE (Tastes), as the taste and preferences of consumers have shifted due to the influencers' claim. For the supply side, consider the headline: 'Semiconductor chip shortage woes: automobile manufacturers warn of delays in production and higher prices.' This suggests a decrease in the supply of semiconductor chips. In the supply graph titled 'Market for Semiconductor Chips', the supply curve shifts to the left from S to S1, indicating a decrease in supply. The new equilibrium price (P1) is higher, and the new equilibrium quantity (Q1) is lower than the initial equilibrium price (Pe) and quantity (Qe). This is an example of change due to ROTTEN (Resources), as resources (semiconductor chips) have become scarcer.

Many products. such as candy. soft drinks. and gum are sold via intensive distribution. However. this strategy has a major drawback. What is it?A) High distribution costsB) Limited market coverageC) Low customer satisfactionD) Difficulty in finding suitable retailersE) Decreased brand awareness

Answers

The major drawback of the intensive distribution strategy is limited market coverage. So, correct option is B.

While this strategy aims to make the product available in as many retail outlets as possible, it may not necessarily reach all potential customers or market segments.

This is because not all retailers may be interested in carrying the product or have the shelf space available to do so. In addition, some customers may prefer to shop at specialized retailers or online, which may not be part of the intensive distribution network.

Furthermore, the high number of retailers and distribution channels involved in an intensive distribution strategy can also lead to high distribution costs.

This is because manufacturers may need to use intermediaries such as wholesalers or distributors to reach all retailers, which can increase the overall costs of distribution.

Despite these drawbacks, intensive distribution can be an effective strategy for products that have mass appeal and are purchased frequently by consumers.

So, correct option is B.

Brenda opens a pool and spa store in a lively shopping mall and finds business to be booming, but she often stocks out of key items customers want. She decides to experiment with inventory control methods such as using a fixed order quantity (FQS) and/or fixed order period (FPS) systems. The 28-ounce bottle of Super Algaecide (SA) is a high margin stock keeping unit (SKU), but it stocks out frequently. Ten SA bottles come in each box, and she orders boxes from a vendor 160 miles away. Brenda is busy running the store and seldom has time to review store inventory status and order the right quantity at the right time. She collects the following data with respect to these SA sales.
Demand = 10 boxes per week Store operates 50 weeks/year
Order cost = $40/order Lead time = 3 weeks
Item cost = $80/box Std. deviation in weekly demand = 6
Inventory-holding cost = 15% per year Service level = 95% (Z=1.645)
A. The Economic Order Quantity (EOQ) rounded to the next highest number is:
B. The reorder point point for Super Algaecide (SA) With safety Stock rounded to the next highest number is:

Answers

The Economic Order Quantity (EOQ) rounded to the next highest number is approximately 186 boxes. The reorder point for Super Algaecide (SA) with safety stock rounded to the next highest number is approximately 40 boxes.

A. The Economic Order Quantity (EOQ) rounded to the next highest number is:

The Economic Order Quantity (EOQ) is a formula used to determine the optimal order quantity that minimizes total inventory costs. The formula for EOQ is:

EOQ = sqrt((2 * Demand * Order cost) / Holding cost per unit)

Given the following information:

Demand = 10 boxes per week

Order cost = $40/order

Inventory-holding cost = 15% per year

Item cost = $80/box

First, we need to convert the holding cost per year to the holding cost per unit per week:

Holding cost per unit per week = (Holding cost per unit * Item cost) / (52 weeks/year)

Holding cost per unit per week = (0.15 * 80) / 52 ≈ 0.2308

Now, we can calculate the EOQ:

EOQ = sqrt((2 * 10 * 40) / 0.2308)

= sqrt(8000 / 0.2308)

≈ sqrt(34622.776)

Rounding up to the next highest number, the Economic Order Quantity (EOQ) is approximately 186.

B. The reorder point for Super Algaecide (SA) with safety stock rounded to the next highest number is:

The reorder point is the inventory level at which a new order should be placed to replenish the stock. It is calculated using the following formula:

Reorder point = (Demand per week * Lead time in weeks) + Safety stock

Given the following information:

Demand per week = 10 boxes

Lead time = 3 weeks

Service level = 95% (Z = 1.645)

Standard deviation in weekly demand = 6

Safety stock = (Z * Standard deviation in weekly demand)

Safety stock = (1.645 * 6)

= 9.87 (rounded to 9)

Reorder point = (10 * 3) + 9

= 39

Rounding up to the next highest number, the reorder point for Super Algaecide (SA) with safety stock is approximately 40 boxes.

you are preparing a cost estimate for a building based on its location, purpose, number of square feet, and other characteristics. what cost estimating technique are you using?

Answers

The cost estimating technique that you are using to prepare a cost estimate for a building based on its location, purpose, number of square feet, and other characteristics is known as parametric estimating.

Parametric estimating involves using historical data and statistical relationships to estimate costs based on specific project parameters. In this case, you would analyze data from similar building projects to identify cost patterns and correlations with factors such as location, purpose, and square footage. By quantifying these relationships, you can develop formulas or models that can be applied to estimate the cost of the building you are working on.

For example, you might find that buildings in a certain location tend to have higher construction costs due to labor or material expenses. Or you might determine that the purpose of the building, such as a hospital versus an office building, affects the cost per square foot. By incorporating these factors into your estimate, you can provide a more accurate cost projection.

In summary, by using parametric estimating, you can leverage historical data and statistical relationships to estimate the cost of a building based on its location, purpose, number of square feet, and other relevant characteristics.

Capital gain and different investment earnings range based on the source of the profit. Capital gains are the returns earned while an investment is bought for more than its purchase price. Funding earnings is take advantage of interest payments, dividends, capital profits, and another earnings made through an funding vehicle.Capital profits taxes follow only to “capital assets,” which include stocks, bonds, rings, coin collections, and actual estate. long-term gains are levied on profits of investments held for extra than a yr. quick-term gains are taxed on the person's regular income tax fee.

Subtract your foundation (what you paid) from the found out quantity (how an awful lot you offered it for) to determine the difference. if you sold your assets for more than you paid, you have a capital benefit. if you bought your assets for less than you paid, you have a capital loss.

Examples include a domestic, personal-use items like family furnishings, and stocks or bonds held as investments. when you promote a capital asset, the difference between the adjusted basis in the asset and the amount you realized from the sale is a capital gain or a capital loss.
