Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim.

The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 lb. Assuming that is known to be 121.2 lb, use a 0.10 significance level to test the claim that the population mean of all such employees weights is less than 200 lb.

A) H0: = 200; H1: >200; Test statistic: z = 0.98. P-value: 0.1234. Reject H0. There is sufficient evidence to support the claim that the mean is less than 200 pounds.

B) H0: = 200; H1: < 200; Test statistic: z = -0.98. P-value: 0.1635. Fail to reject H0. There is not sufficient evidence to support the claim that the mean is less than 200 pounds.
