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
