The manager of a warehouse monitors shipments. The automated tracking system monitors every package as it moves through the facility. A sample of 25 packages is selected and weighed every day. On the basis of contracts with customers, the mean weight should be u= 22 pounds with o = 5 pounds. Mark the following statement as true or false. If you believe that the statement is false, briefly say why you think it is false. Before using a normal model for the sampling distribution of the average package weights, the manager must confirm that weights of individual packages are normally distributed. Choose the correct answer below. O A. The statement is false because the individual values do not need to be normally distributed as long as the sample size condition is satisfied (n> 10|K) O B. The statement is false because the individual values do not need to be normally distributed as long as the sample size condition is satisfied (n> |K) O C. The statement is true. O D. The statement is false because there are no requirements for using a normal model.

The manager of a warehouse monitors shipments. The automated tracking system monitors every package as it moves through the facility. A sample of 25 packages is
selected and weighed every day. On the basis of contracts with customers, the mean weight should be u= 22 pounds with o = 5 pounds. Mark the following statement as
true or false. If you believe that the statement is false, briefly say why you think it is false.
Before using a normal model for the sampling distribution of the average package weights, the manager must confirm that weights of individual packages are normally
distributed.
Choose the correct answer below.
O A. The statement is false because the individual values do not need to be normally distributed as long as the sample size condition is satisfied (n> 10|K)
O B. The statement is false because the individual values do not need to be normally distributed as long as the sample size condition is satisfied (n> |K)
O C. The statement is true.
O D. The statement is false because there are no requirements for using a normal model.
