Poverty and Calcium: A simple random sample of 18 people with incomes below the poverty level gives the following daily calcium intake:

686 423 743 647 734 641

993 620 574 634 850 858

992 775 1113 672 879 609

At the 5% significance level do the data provides sufficient evidence to conclude that the mean calcium intake of all people with incomes below the poverty level is less than the RDA of 800 mg? Perform a Hypothesis Test.
