If you meet all the criteria for an independent t-test but do not satisfy the assumption of normality, you should technically do a non-parametric test instead of an independent t-test.

So, the correct answer is D.

Non-parametric tests do not require the data to be normally distributed, unlike parametric tests such as t-tests. Non-parametric tests include the Mann-Whitney U test, Wilcoxon rank-sum test, and Kruskal-Wallis test.

These tests are based on ranks rather than the actual values of the data and are generally less powerful than parametric tests, meaning that they may require larger sample sizes to achieve the same level of statistical significance.

It is important to choose the appropriate statistical test for your data to ensure accurate results and conclusions. Simply redoing the experiment or ignoring the violation of the normality assumption is not a valid solution.

The total fixed costs for the event amount to £2,800, which includes the security costs and the cost of the main band. Fixed costs are expenses that do not change with the number of attendees or sales.

To calculate the total fixed costs for the event, we need to identify the costs that do not change with the number of attendees. Based on the given information, the fixed costs include the security costs and the cost of the main band. Let's break it down:

Security costs: The security costs of £300 are fixed and do not depend on the number of attendees. This means the cost remains the same regardless of how many tickets are sold.

Cost of the main band: The cost of the main band is £2,500. Similar to the security costs, this cost is fixed and does not vary based on the number of attendees.

Therefore, the total fixed costs for the event would be the sum of the security costs and the cost of the main band:

Total Fixed Costs = Security Costs + Cost of Main Band

Total Fixed Costs = £300 + £2,500

Total Fixed Costs = £2,800

However, it's important to note that the cost of the supporting band, ticket prices, and the cost of the water bottles are not fixed costs. The cost of the supporting band and the cost of the water bottles are variable costs as they depend on the number of attendees. The ticket prices represent revenue, not costs.

Given the triangle with side lengths \(\( b = 25 \), \( c = 30 \),\) and angle \(\( B = 25^\circ \),\) we can solve for the remaining elements of the triangle.

The angle \(\( A \)\) is approximately \(\( 68.62^\circ \),\) the angle \(\( C \)\) is approximately \(\( 86.38^\circ \)\), and the side length \(\( a \)\) is approximately \(\( 19.71 \).\)

To solve for the triangle, we can use the Law of Sines and the fact that the sum of angles in a triangle is \(\( 180^\circ \).\)

First, we can use the Law of Sines to find the remaining angle \(\( A \).\) The Law of Sines states that \(\( \frac{a}{\sin A} = \frac{c}{\sin C} \).\) Plugging in the given values, we have \(\( \frac{25}{\sin 25^\circ} = \frac{30}{\sin C} \).\) Solving for \(\( \sin C \),\) we find \(\( \sin C \approx 0.8693 \).\) Taking the inverse sine, we get \(\( C \approx 60.13^\circ \).\) Since the sum of angles in a triangle is \(\( 180^\circ \),\) we can find \(\( A \)\) by subtracting \(\( B \)\) and \(\( C \)\) from \(\( 180^\circ \).\)

Next, we can use the Law of Sines again to find the length of side \(\( a \).\)Rearranging the formula, we have \(\( \frac{a}{\sin A} = \frac{c}{\sin C} \).\) Plugging in the known values, we get \(\( \frac{a}{\sin A} = \frac{30}{\sin 60.13^\circ} \).\) Solving for \(\( a \),\) we find \(\( a \approx 19.71 \).\)

Therefore, the triangle has angles \(\( A \approx 68.62^\circ \), \( B = 25^\circ \), \( C \approx 86.38^\circ \),\) and side lengths \(\( a \approx 19.71 \), \( b = 25 \), \( c = 30 \).\)

The system of equations is consistent and has a unique solution at (-4, 1).

To solve the system of equations by graphing, we can plot the lines represented by each equation on a coordinate plane and find their point of intersection.

The given system of equations is:

1) 3x + y = -3

2) 6x - 6y = -30

Let's graph these equations:

For equation 1, 3x + y = -3, we can rewrite it as y = -3x - 3.

For equation 2, 6x - 6y = -30, we can simplify it to x - y = -5, and then y = x + 5.

Now, let's plot these lines on a graph:

The line for equation 1, y = -3x - 3, has a slope of -3 and y-intercept of -3. It will have a negative slope, and we can plot two points on the line: (0, -3) and (-1, 0).

The line for equation 2, y = x + 5, has a slope of 1 and y-intercept of 5. We can plot two points on this line as well: (0, 5) and (-5, 0).

Plotting these lines on a graph, we can see that they intersect at the point (-4, 1).

Now, let's analyze the system:

Since the lines intersect at a single point, the system is consistent. The solution to the system is the coordinates of the point of intersection, which is (-4, 1).

In summary, the system of equations is consistent and has a unique solution of x = -4 and y = 1.

We know that the power of x in the leading term is even and its coefficient is positive, therefore the end behavior of the polynomial is that it goes up on both sides of the graph, which means the graph is in the shape of a U.

So the graph of the polynomial will look like U, opening upwards. In the graph, the right arm of the U will go up in the positive direction and the left arm will go up in the negative direction.

To find the zeros of the given polynomial:  f(x) = x4 -8x² + 16 First, let’s simplify the polynomial by factoring out 16. f(x) = x4 -8x² + 16 = x4 -8x² -16 + 32 Next, let’s use substitution method and try a few values for x until we find a value that makes the equation equal to zero.

By substituting x=2, we get f(2) = 16 - 32 + 16 = 0So x = 2 is a zero of f(x). We know that 2 is a zero of f(x), so we can factor f(x) using synthetic division.    2 | 1 0 -8 0 16   | 1 2 -4 0 16             1 2 -6 0 32.\

The quotient is x³ + 2x² - 6x and the remainder is zero

. Therefore,  x⁴ - 8x² + 16 = (x - 2)(x³ + 2x² - 6x + 8)  x = 2 is a zero of multiplicity 1. Next, we find the zeros of x³ + 2x² - 6x + 8 using the rational roots theorem.

The factors of 8 are ± 1, ± 2, ± 4, and ± 8. The factors of 1 are ± 1, so the possible rational roots are: ± 1, ± 2, ± 4, ± 8   x | 1 2 -6 8   | 1 3 3 -3  .

The quotient is x² + 3x + 3 and the remainder is -3. Therefore, x³ + 2x² - 6x + 8 = (x + 1)(x² + 3x + 3)  The zeros are:  x = 2 (multiplicity 1), and x = -1 + i and x = -1 - i (multiplicity 1 for each). Now we know that the graph of f(x) will intersect the x-axis at x = -1+i, -1-i, 2 (multiplicity 1).

The multiplicity of a zero represents the number of times that factor is repeated. In other words, it tells us how many times the graph touches or crosses the x-axis at that zero.

If the multiplicity of a zero is even, then the graph will touch the x-axis at that zero and turn back. If the multiplicity of a zero is odd, then the graph will cross the x-axis at that zero.

We know that the zero x = 2 has multiplicity 1, so the graph will cross the x-axis at x = 2.

We know that the zeros x = -1+i and x = -1-i have multiplicity 1 for each, so the graph will cross the x-axis at x = -1+i and x = -1-i.

The y-intercept is the point at which the graph crosses the y-axis. To find the y-intercept, we can set x = 0 and solve for y. f(0) = 0⁴ - 8(0)² + 16 = 16The y-intercept is (0, 16).

We can find additional points by setting x to some other values and solving for y. For example: x = 1, f(1) = 1⁴ - 8(1)² + 16 = 9The point is (1, 9). x = -1, f(-1) = (-1)⁴ - 8(-1)² + 16 = 9The point is (-1, 9). x = 3, f(3) = 3⁴ - 8(3)² + 16 = 25The point is (3, 25). x = -2, f(-2) = (-2)⁴ - 8(-2)² + 16 = 36The point is (-2, 36).

Using all this information, we can sketch the graph of f(x):

To sketch the end behavior of a polynomial, we need to look at the leading term of the polynomial. The leading term is the term with the highest degree. The degree of a term is the sum of the exponents of its variables.

For example, in the polynomial f(x) = 3x³ - 5x² + 2x - 1, the leading term is 3x³ because it has the highest degree. The degree of the leading term is 3 because it is a cubic polynomial.

The coefficient of the leading term is 3. The end behavior of a polynomial is determined by the degree and the sign of the coefficient of the leading term.

If the degree of the leading term is even and the coefficient is positive, then the end behavior is up on both sides of the graph, which means the graph is in the shape of a U, opening upwards.

If the degree of the leading term is odd and the coefficient is positive, then the end behavior is up on the left side of the graph and down on the right side of the graph, which means the graph is in the shape of an N, opening upwards.

If the coefficient of the leading term is negative, then the graph is in the shape of a U or N, but it is flipped upside down, so the end behavior is down on both sides of the graph (for a U-shaped graph) or down on the left side and up on the right side (for an N-shaped graph).

In conclusion, we can sketch the end behavior of a polynomial by looking at the leading term. We can find the zeros of a polynomial by factoring or using the rational roots theorem. The multiplicity of a zero tells us how many times the graph touches or crosses the x-axis at that zero. The y-intercept is the point at which the graph crosses the y-axis. Additional points can be found by setting x to some other values and solving for y. By using all this information, we can sketch the graph of a polynomial.

In the △IGH, the measurement of the angles are m∠G = 114°, m∠H = 49°, and m∠I = 17°.

What is an angle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given that,

m∠G = (7x - 5)°, m∠H = (3x - 2)°, and m∠I = x°.

The sum of interior angles of a triangle is 180°.

Therefore,

m∠G + m∠H + m∠I = 180°

Putting m∠G = (7x - 5)°, m∠H = (3x - 2)°, and m∠I = x°:

(7x - 5)° + (3x - 2)° + x° = 180°

Combine like terms:

(7x + 3x + x) - (5 + 2) =180

11x - 7 = 180

Add 7 on both sides:

11x = 187

Divide both sides by 11:

x = 187/11

x = 17

Now putting x = 17 in m∠G = (7x - 5)°, m∠H = (3x - 2)°, and m∠I = x°:

m∠G = (7×17 - 5)° = 114°

, m∠H = (3×17  - 2)° = 49°

m∠I =  17°

Given that X N(300, 15), find the Interquartile Range (IQR).

The given distribution is normal with mean μ = 300 and standard deviation σ = 15.

We need to calculate the interquartile range (IQR).IQR is defined as the difference between the third quartile (Q3) and the first quartile (Q1).

The first quartile (Q1) is the value below which 25% of the data fall and the third quartile (Q3) is the value below which 75% of the data fall.

We can find these values using the standard normal distribution table.

For the first quartile,

z1 = invNorm(0.25)

= -0.67449

Q1 = μ + σ × z1

= 300 + 15 × (-0.67449)

= 289.88

≈ 289.89

For the third quartile,

z3 = invNorm(0.75)

= 0.67449

Q3 = μ + σ × z3

= 300 + 15 × 0.67449

= 310.12

Therefore, the interquartile range (IQR)

= Q3 – Q1

= 310.12 – 289.89

(a) To find the vectors AB and AC, we subtract the coordinates of point A from the coordinates of points B and C, respectively:

Vector AB = B - A = (2 - 4, 0 - 1, 3 - (-2)) = (-2, -1, 5)

Vector AC = C - A = (-1 - 4, 2 - 1, 3 - (-2)) = (-5, 1, 5)

(b) The parametric equation of the line passing through points A and B can be expressed as:

x = 4 - 2t

y = 1 - t

z = -2 + 5t

The equation of the plane containing points A, B, and C can be determined using the cross product of vectors AB and AC. The normal vector of the plane is given by:

n = AB x AC = (-2, -1, 5) x (-5, 1, 5)

Using the cross product formula, we calculate the cross product:

n = ((-1)(5) - (1)(-5), (5)(-5) - (5)(-2), (-2)(1) - (-1)(-2))

= (-5 - (-5), -25 - (-10), -2 - 2)

= (0, -15, 0)

The equation of the plane can be written as:

0x - 15y + 0z + d = 0

Simplifying, we get:

-15y = 0

y = 0

Therefore, the equation of the plane is -15y = 0, or simply y = 0.

(c) To find the area of triangle ABC, we can use the formula:

Area = (1/2) * |AB x AC|

We already have the vectors AB and AC:

AB = (-2, -1, 5)

AC = (-5, 1, 5)

Calculating the cross product:

AB x AC = ((-1)(5) - (1)(-5), (5)(-5) - (5)(-2), (-2)(1) - (-1)(-2))

= (-5 - (-5), -25 - (-10), -2 - 2)

= (0, -15, 0)

Now we can find the magnitude of the cross product:

|AB x AC| = sqrt(0^2 + (-15)^2 + 0^2) = sqrt(225) = 15

Finally, we calculate the area:

Area = (1/2) * |AB x AC| = (1/2) * 15 = 7.5

Therefore, the area of triangle ABC is 7.5 square units.
