Question

Test the given claim. Identify the null hypothesis, alternative hypothesis, critical values, and conclusion. Sketch the graphto confirm your solution. The health of employees in the given company is monitored by periodically weighing them in. A sample of 54 employeeshas a mean weight of 183.9lb. Assuming that the standard deviation of all employees in the indicated company 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.

Explanation / Answer

Null Hypothesis - Population Mean of employees weights is less than 200 lb.

Alternative Hypothesis - Population Mean of employees weights is not less than 200 lb.

Critical Values - The z score is -0.97616.

The p value is 0.16354.

The result is not significant at p <0.10.

Hence the given hypothesis is not true.
