In a clinical trial, 23 out of 821 patients taking a prescription drug daily complained of flu-like symptoms. Suppose that it is known that 2.5% of patients taking competing drugs complain of flu-like symptoms. Is there sufficient evidence to conclude that more than 2.5% of this drug's users experience flu-like symptoms as a side effect at the alpha equals 0.1 level of significance? Because np(1-p) equals 20.0, which is greater than 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? Upper H0: p equals 0.025 versus Upper H1: p greater than 0.025. Find the test statistic, z0. (Round to two decimal places as needed)
