3! Researchers selected 886 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial. 21 out of the 836 patients complained of ulike symptoms. Suppose that it Is known that 2.1 % of patients taking competing drugs complain of ulike symptoms. is there sufcient evidence to conclude that more than 2.1% of this drug's users experience ulike symptoms as a side sites! at the a=0.1 level of signicance? l 4 Assume that the population is large and the sample is obtained randomly. Because npo(1- p0) = I] 10 and the sample size Is 5% of the population size, the requirements for testing the hypothesis satised. (Round to one decimal place as needed.) What are the null and alternative hypotheses? HoIIIDversuswED t (Type integers or decimals. Do not round.) " Find the test statistic, 20. 20 = D (Round to two decimal places as needed.) Find the P-vaiue. Pvalue = E] (Round to three decimal places as needed.) State the conclusion. Since the Pvalue is 'j o. E the null hypothesis and conclude that there sufcient evidence that 2.1 \"In of the users experience ulike symptoms. Interpretthe P-value. if this study was conducted 100 independent times and the statement in the null hypothesis were true, then we would expect to observe a sample proportion of D or higher in about [E of the studies. (Round to three decimal places as needed.)
