1. Salt intake and CVD. Suppose we are interested in investigating the relationship between high salt intake and death from cardiovascular disease (CVD). Dare collected on men ages 50-54 who died over a 1-month period. Of 35 men who died from CVD, 5 had a diet with high salt intake before they died, while of the 25 men who died from other causes, 2 had a diet with high salt intake. These data are summarized in the following table.

	CVD Death	Non-CVD Death	Total
High Salt Diet	5	2	7
Low Salt Diet	30	23	53
Total	35	25	60

a. State the hypotheses.

b. Using Stata commandtabi, calculate expected frequencies and determine which test is the most appropriate test to answer the research question.

c. According to the test in (b), report p-value. What is your conclusion? Interpret.
