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.

In a two-way factorial design analysis, there are two main effects tested.

A two-way factorial design involves the simultaneous manipulation of two independent variables, each with multiple levels, to study their individual and combined effects on a dependent variable. The main effects in such a design represent the effects of each independent variable independently, ignoring the influence of the other variable.

When conducting a two-way factorial design analysis, there are two main effects tested, corresponding to each independent variable. The main effect of one variable is the difference in the means across its levels, averaged over all levels of the other variable. Similarly, the main effect of the other variable is the difference in the means across its levels, averaged over all levels of the first variable.

Testing the main effects allows researchers to determine the individual impact of each independent variable on the dependent variable, providing insights into their overall influence. By analyzing the main effects, researchers can assess the significance and directionality of the effects, aiding in the interpretation of the experimental results and understanding the relationship between the independent and dependent variables in the factorial design.

Answer:

120 mm²

800 in.²

Step-by-step explanation:

Upper figure:

Large rectangle in the middle:

    length = 5 mm + 6 mm + 5 mm = 16 mm

    width = 6 mm

    area = 16 mm × 6 mm = 96 mm²

2 congruent triangles:

    base = 6 mm

    height = 4 mm

    area of each triangle = 6 mm × 4 mm / 2 = 12 mm²

Total area of net = 96 mm² + 2 × 12 mm² = 120 mm²

Lower figure:

Square in the middle:

    side = 16 in.

    area = 16 in. × 16 in. = 256 in.²

4 congruent triangles:

    base = 16 in.

    height = 17 in.

    area of each triangle = 16 in. × 17 in. / 2 = 136 in.²

The statement "the first step in the sampling design process is to determine the sample size" is false because according to the text, the first step in the sampling design process is to clearly define the target population.

The first step in the sampling design process is typically to define the target population and the research objectives.

This involves specifying the characteristics of the population under study and identifying the specific research questions or objectives that the sampling will address.

Once the target population and research objectives are established, the next steps in the sampling design process typically involve determining the appropriate sampling method (such as random sampling, stratified sampling, or cluster sampling) and selecting the sampling frame (the list or source from which the sample will be drawn).

After these initial steps, researchers can then consider factors such as the desired level of precision, confidence level, and variability in the population to determine the appropriate sample size.

The determination of the sample size usually comes after clarifying the research objectives and selecting the appropriate sampling method.

Step-by-step explanation:

Chris can afford to use 500 minutes with a monthly bill of $86.00, given the flat fee of $26.00 per month and a cost of $0.12 per minute of usage.

To determine the number of minutes of usage Chris can afford with a monthly bill of $86.00, we need to subtract the flat fee from the total bill and then divide the remaining amount by the cost per minute.

Let's calculate it-

1. Subtract the flat fee from the total bill:

$86.00 - $26.00 = $60.00

2. Divide the remaining amount by the cost per minute:

$60.00 ÷ $0.12 = 500 minutes

Therefore, Chris can afford to use 500 minutes with a monthly bill of $86.00, given the flat fee of $26.00 per month and a cost of $0.12 per minute of usage.

The series is divergent.Explanation  The given series is (-1)^n * (2n + 1)! + 1 / (2n). To determine its convergence, we can consider the limit of the general term as n approaches infinity.Taking the limit of the absolute value of the general term:

lim(n→∞) |(-1)^n * (2n + 1)! + 1 / (2n)| = lim(n→∞) (2n + 1)! / (2n)

As n approaches infinity, the term (2n + 1)! grows faster than (2n), resulting in the limit approaching infinity. Therefore, the general term does not approach zero, indicating that the series diverges.Since the series diverges, it does not have a finite sum. The terms do not approach a specific value as the number of terms increases.

You are c) a structure. A structure is a collection of one or more different types of variables, including arrays and pointers, that have been grouped under a single name for each manipulation.

A structure is a user-defined data type that allows you to group together related data. For example, you could create a structure to store the name, age, and address of a person. The structure would have three variables, each of a different type: a string variable for the name, an integer variable for the age, and a string variable for the address.

The advantage of using a structure is that it allows you to treat the related data as a single unit. This makes it easier to manipulate the data and to pass the data to functions.

The other answer choices are incorrect. A template is a blueprint for creating a generic class or function. An array is a collection of elements of the same type. Local variables are variables that are declared within a function and that are only accessible within the function.

To find a formula for the linear operator T, we need to determine how it acts on the standard basis vectors of R^2, i.e., T(1, 0) and T(0, 1). Let's calculate:

T(1, 0) = T(1 * (1, 0)) = 1 * T(1, 0) = (1 * T(1, 0), 0 * T(1, 0)) = (a, b),

where a and b are unknown coefficients.

Similarly,

T(0, 1) = T(1 * (0, 1)) = 1 * T(0, 1) = (0 * T(0, 1), 1 * T(0, 1)) = (c, d),

where c and d are unknown coefficients.

From the given information, we have:

T(1, 1) = (2, 2) = 2 * (1, 0) + 2 * (0, 1) = (2 * T(1, 0), 2 * T(0, 1)) = (2a, 2c).

T(2, 1) = (4, 5) = 4 * (1, 0) + 5 * (0, 1) = (4 * T(1, 0), 5 * T(0, 1)) = (4a, 5c).

By comparing the coefficients, we can determine the values of a, c, b, and d.

From T(1, 1), we have:

2a = 2  => a = 1.

From T(2, 1), we have:

4a = 4  => a = 1.

So, we have determined that a = 1.

From T(1, 1), we have:

2c = 2  => c = 1.

From T(2, 1), we have:

5c = 5  => c = 1.

So, we have determined that c = 1.

Now, we can write T(x, y) as a linear combination of T(1, 0) and T(0, 1):

T(x, y) = x * T(1, 0) + y * T(0, 1)

        = x * (1, 0) + y * (0, 1)

        = (x, 0) + (0, y)

        = (x, y).

Therefore, the formula for T(x, y) is simply T(x, y) = (x, y), where (x, y) represents the vector in R^2.

Question 9) \(y=\frac{-3}{2}x+2 \\\\\)

Question 10) \(y=-x-6\\\)

Step-by-step explanation:

Well there are two methods of determining an equation of line

Method 1 (Using the slope-intercept form):

\(y=mx+b\)

This method is mostly used when the y-intercept also known as b is given and the slope also known as m is given

Method 2 (Using the point-slope form):

\(y-y_1=m(x-x_1)\\\)

This method is used when a point is given also known as (x1 , y1) and the slope is given which is denoted by m.

Since in Question 9 there is no y-intercept given only two points we will use the second method so here goes,

Q9)

Two points are  (0 , 2) and (4 , -4) first step to find out the equation of line is to calculate the slope which is as follows:

\(m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-4-2}{4-0} \\\\m=\frac{-6}{4}\\\\m=-3/2 \\\)

Now we have our slope which is m = -3/2 now since we have two points we can use any point in the point-slope form equation because both of these points lie on the line hence satisfying the desired equation that we need so we select the point (0 , 2) [YOU CAN TRY OUT FINDING THE EQUATION OF LINE BY USING THE OTHER POINT THE ANSWERS WOULD BE SAME]

so now we have the point (0 , 2) and value of m = -3/2

\(y-y_1=m(x-x_1)\\y-2=\frac{-3}{2}(x-0)\\\\y-2=\frac{-3}{2}x\\\\y=\frac{-3}{2}x+2\\\\\)

Question 10)

Two points are (-2 , -4) and (-3 , -3) we use the same method as shown above,

First step calculate the slope:

\(m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-3-(-4)}{-3-(-2)} \\\\m=\frac{-3+4}{-3+2}\\\\m=1/-1\\\\m=-1\\\)

now we insert the value of m = -1 and take any point of the two points that are given, we select the first point (-2 , -4)

\(y-y_1=m(x-x_1)\\y-(-4)=(-1)(x-(-2))\\y+4=(-1)(x+2)\\y+4=-x-2\\y=-x-2-4\\y=-x-6\\\)

The point (-2,2), we need to evaluate each case

In this case, for the real part we need to obtain -2

For the imaginary part, we need to obtain 2
