Researchers selected 867 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial, 20 out of the 867 patients complained of flulike symptoms. Suppose that it is known that 1.8% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 1.8% of this drug's users experience flulike symptoms as a side effect at the a=0.01 level of significance? Because npo (1-Po) 15.3 10, the sample size is less than 5% of the population size, and the patients in the sample the requirements for testing the hypothesis (Round to one decimal place as needed.) What are the null and alternative hypotheses? are satisfied. Ho p ery 0.018 versus H, P > 0.018 (Type integers or decimals. Do not round.) Find the test statistic, zo- Zo (Round to two decimal places as needed.) were selected at random, all of
