Answer to Problem 1.1SR

The maximum numbers of employees per store is 105 employees.

The minimum numbers of employees per store is 79 employees.

Explanation of Solution

In the dotplot of number of employees for each of 142 Home Depot stores, the horizontal line represents ‘Number of employees’.

From dotplot, it can be observed that, the maximum or largest number of employees for one of the store is 105 employees. Also, the minimum or smallest number of employees for one of the store is 79 employees.

Hence, the maximum numbers of employees per store is 105 employees and the minimum numbers of employees per store is 79 employees.

(b)

To determine

Find the number of stores that employ 91 people.

(b)

Expert Solution

Answer to Problem 1.1SR

The number of stores that employ 91 people is 15 stores.

Explanation of Solution

In the dotplot of number of employees, count the number of dots corresponding to 91 employees on the horizontal line. The number of dots corresponding to 91 employees is 15.

Hence, the number of stores that employ 91 people is 15 stores.

(c)

To determine

Identify around what values the number of employees per store tends to cluster.

(c)

Expert Solution

Answer to Problem 1.1SR

The values around which the number of employees per store tends to cluster are 88 employees to 97 employees.

Explanation of Solution

From dotplot, it can be observed that, most of the stores have about 88 to 97 employees. The ‘number of employees for each store’ is clustered around the values 88 to 97, because approximately 75% of the stores are covered under this range.

Hence, the values around which the number of employees per store tends to cluster are 88 employees to 97 employees.

Suppose the Internal Revenue Service reported that the mean tax refund for the year 2022 was $3401. Assume the standard deviation is $82.5 and that the amounts refunded follow a normal probability distribution. Solve the following three parts? (For the answer to question 14, 15, and 16, start with making a bell curve. Identify on the bell curve where is mean, X, and area(s) to be determined. 1.What percent of the refunds are more than $3,500? 2. What percent of the refunds are more than $3500 but less than $3579? 3. What percent of the refunds are more than $3325 but less than $3579?
A normal distribution has a mean of 50 and a standard deviation of 4. Solve the following three parts? 1. Compute the probability of a value between 44.0 and 55.0. (The question requires finding probability value between 44 and 55. Solve it in 3 steps. In the first step, use the above formula and x = 44, calculate probability value. In the second step repeat the first step with the only difference that x=55. In the third step, subtract the answer of the first part from the answer of the second part.) 2. Compute the probability of a value greater than 55.0. Use the same formula, x=55 and subtract the answer from 1. 3. Compute the probability of a value between 52.0 and 55.0. (The question requires finding probability value between 52 and 55. Solve it in 3 steps. In the first step, use the above formula and x = 52, calculate probability value. In the second step repeat the first step with the only difference that x=55. In the third step, subtract the answer of the first part from the…
