Question

In a clinical trial, 22 out of 897 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.1% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.1% of this drug's users experience flulike symptoms as a side effect at the a = 0.01 level of significance? less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied. Because npo (1-Po) = 18.4 > 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: versus H : (Type integers or decimals. Do not round.)
