Demand in each period follows the same normal distribution (i.e., there is one demand distribution that represents demand in any single period). Assuming demand is independent across periods, which of the following statements about mean demand over five periods is true? a. It equals the mean of demand over one period. b. It is greater than the mean of demand over one period but less than five times the mean of demand over one period. c. It equals five times the mean of demand over one period. d. It is even more than five times the mean of demand over one period.

Demand in each period follows the same normal distribution (i.e., there is one demand distribution that represents demand in any single period). Assuming demand is independent across periods, which of the following statements about mean demand over five periods is true?

a. It equals the mean of demand over one period.
b. It is greater than the mean of demand over one period but less than five times the mean of demand over one period.
c. It equals five times the mean of demand over one period.
d. It is even more than five times the mean of demand over one period.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

Expert Solution & Answer

Summary Introduction

To identify: The statement that is true regarding the mean demand over five periods.

Explanation of Solution

Correct option: (c)

Correct answer:

It equals five times the mean of demand over one period.

Justification:

The demand follows the same normal distribution over the five periods. It is also assumed that the demand is independent across the periods. The mean of demand across multiple periods will be equal to the sum of the means of the demand of the individual periods. All the periods will have the same mean demand. Therefore, the demand over 5 periods will be equal to 5 times the demand in a single period.

What should leaders do after conducting an employee survey? take immediate action on results take at least 6 months to review the results to make sure the leader understands them review them immediately, but do not take action right away keep results confidential from employees

One of the best ways to encourage teamwork is to: continually promote from outside of the department recognize employees who focus on their personal performance goals only reward employees who complete their own tasks and also assist with problems outside of their department discuss individual performance issues at staff meetings

What can happen if a leader doesn't encourage teamwork? team members will support each other more the environment can become overly competitive and hostile turnover will descrease team members become more motivated
