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

Assume that a simple random sample has been selected from a normally distributed population. Test the mean about the population using Traditional method for Hypothesis testing (indicate the null hypothesis, Alternative hypothesis, test statistic, critical value conclusion about null hypothesis and final conclusion that addresses the original claim.
