In a clinical trial, 23 out of 869 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.2% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.2% of this drug's users experience flulike symptoms as a side effect at the a = 0.05 level of significance? Because npo (1 - Po ) = 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho : versus Hy: (Type integers or decimals. Do not round.) Find the test statistic, Zo- zo =(Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.)
