In an epidemiologic study, 147 incident breast cancer cases were compared to 179 controls selected from the population that gave rise to the cases with respect to alcohol consumption history. The data were as follows:

Exposure status	Disease Status
Case	Control	Total
> 3 drinks/day	75	87	162
Nondrinker	72	92	164
Total	147	179	326

Perform the appropriate statistical test of the relationship between breast cancer and alcohol consumption history using SAS. Assume = 0.05 (two-tailed) and 80% power.

a) State the null and alternative hypotheses.

b) List the critical value.

c) List the estimated odds ratio.

Using the uncorrected chi-square, P-value, and odds ratio output from SAS, report your decision (reject Ho and accept H_A OR fail to reject Ho) based on the critical value, P-value, and 95% confidence interval for the odds ratio.

d) __________________________________________________________________________

e) __________________________________________________________________________

f)__________________________________________________________________________

g) If the decision was to fail to reject Ho, can Ho be accepted?
