A certain drug is meant to reduce cholesterol and LDL cholesterol. Researchers selected 878 patients at random among those who take this widely-used prescription drug daily. In a clinical trial, 25 out of the 878 patients complained of flulike symptoms. Suppose that it is known that 2.4% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.4% of this drug's users experience flulike symptoms as a side effect at the a=0.05 level of significance? Because npo (1-Po) = 20.6 >10, the sample size is less than 5% of the population size, and the patients in the sample were selected at random, all of the requirements for testing the hypothesis about the population proportion are satisfied (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho P = 0.024 versus H₁: p > 0.024 (Type integers or decimals. Do not round.) Find the test statistic, Zo Zo (Round to two decimal places as needed.)
