Question

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. HO -200: Hsu 200: Test statistic: z-O.98.Pvalue: 0.1234. Reject Ho. There is sufficient evidence to support the claim that the mcan is less than 200 pounds

Explanation / Answer

Below are the null and alternate hypothesis
H0: mu = 200
H1: mu < 200

Test statistics, z = (183.9 - 200)/(121.2/sqrt(54)) = -0.9762

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.
