One survey showed that among 900 randomly selected subjects who completed four years of college, 160 smoke and 740 do not smoke (based on data from the American Medical Association). For this sample p = correct to 4 decimal places. Using a 0.01 significance level to test the claim that the rate of smoking among those with four years of college is less than the 20% rate for the general population, answer the following: Which is the proper expression of Họ?
