In a clinical trial, 27 out of 892 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.7% of patients tak competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.7% of this drug's users experience flulike sympto as a side effect at the a= 0.01 level of significance? Because npo (1-Po) = 23.4 > 10, the sample size is 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 (Round to one decimal place as needed.) What are the null and alternative hypotheses? 0.027 versus H₁: P > 0.027 Ho: Р = (Type integers or decimals. Do not round.) Find the test statistic, Zo- Zo = (Round to two decimal places as needed.)
