Explanation:

Internal validity examines if the planning, carrying out, and analysis of the study yield objective solutions to the research objectives.

What is internal validity?

Internal validity is defined as the level of assurance that the causal link you are evaluating is not affected by additional variables or circumstances. As a result of ignoring confounding factors, high internal validity enables the researcher to select one explanation over another with sufficient confidence.

When three conditions are met the "cause" precedes the "effect" in time, the "cause" and the "effect" tend to occur together, and a valid causal inference may be drawn. There aren't any logical alternatives to the observed covariation.

Thus, internal validity tests whether the study's planning, execution, and analysis provide unbiased answers to the research objectives.

The standard deviation of the sampling distribution of the sample mean length is of:

s = 0.1.

How to obtain the standard deviation of the sample mean?

According to the Central Limit Theorem, the sampling distribution of sample means of size n, from a normally distributed population in which the mean and the standard deviation are known, has these following features:

• Shape: Approximately Normal.

• Mean: Same as population mean.

• Standard deviation: standard deviation of the population divided by the sample size.

In the context of this problem, the values of the parameters are given as follows:

• Standard deviation of the population: 0.4.

• Sample size: 16.

The square root of the sample size is of:

4.

Hence the standard deviation of the sampling distribution of the sample mean length is of:

0.4/4 = 0.1.

About 96.63% of the area under the curve of the standard normal distribution is between z = − 2.124 and z = 2.124 (or within 2.124 standard deviations of the mean).

What is the standard normal distribution?

A continuous probability distribution for a real-valued random variable is called a normal distribution or a Gaussian distribution in statistics. Graphs make it simple to identify the following key traits of normal distributions: The mode, median, and mean are all equal. About the mean, the distribution is symmetric; half of the values are below and half are above the mean. Two numbers, the mean and the standard deviation, can be used to describe the distribution.

An equation to accompany each array is as follows;

(r³ - 3) × 1 = 24, (r² + 3) × 2 = 24, (r² - 1 ) × 3 = 24, (r² - 3 ) × 4 = 24, (r) × 8 = 24, (r - 1 ) × 12 = 24, and (r - 2) × 12 = 24 where, r = 3.

How to model a rectangular array?

The rectangular array will be considered as rows.

Now, when we take the first side as the length represented by L and the second side as the width represented by W.

Area of a rectangle is given by the formula;

Area = length * width

Area = L * W

We are modeling a rectangular quilt with the 24 paper squares and as such the total area of the quilt is 24 squares which means;

24 × 1 = 24

All squares are arranged in a single row;

(r³ - 3) × 1 = 24

12 × 2 = 24

12 squares arranged in 2 rows.

(r² + 3) × 2 = 24

8 × 3 = 24

8 squares arranged in 3 rows.

(r² - 1 ) × 3 = 24

6 × 4 = 24

6 squares arranged in 4 rows.

To determine the minimum number of people the pollster should survey in order to have a margin of error of 10 minutes at 95% confidence, we can use the following formula:

n = (Z^2 * p * (1 - p)) / (E^2)

where:

n = the minimum number of people the pollster should survey

Z = the z-score corresponding to the desired level of confidence (for a 95% confidence level, the z-score is approximately 1.96)

p = the estimated proportion of the population that holds a particular opinion or characteristic (in this case, we will assume that p = 0.5, since we are given that sigma is equal to 30 and we want to find the minimum number of people needed to achieve a margin of error of 10 minutes)

E = the desired margin of error (in this case, E = 10 minutes)

Substituting these values into the formula, we get:

n = (1.96^2 * 0.5 * (1 - 0.5)) / (10^2)

Simplifying this expression, we get:

n = (3.8416 * 0.25) / 100

= 0.09604 / 100

= 0.0009604

Since n must be a whole number, we need to round up to the nearest whole number. In this case, the minimum number of people the pollster should survey is 1.

Therefore, the minimum number of people the pollster should survey in order to have a margin of error of 10 minutes at 95% confidence is 1.

Explanation:

Your project will be completely defined from beginning to end by a problem statement or opportunity statement. Issue Statement: You want to update or improve an existing procedure or service.

What opportunity or Problem project addressing?

Opportunity in relation to a project mostly refers to the value expected from the project output. Initial cost and outcome projections lead to a value expectation that is greater than the project's cost. This disparity may suggest a modestly reasonable prospect or one that is outrageously idealistic.

Therefore, Opportunity Statements are useful when developing new procedures or services.
