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.

= 0.01.

control when defects exceed 3%. In a random sample of 85 items, the
defect rate is 5.9% but the manager claims that this is only a
