In a clinical trial, 18 out of 820 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 1.9% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 1.8% of this drug's users experience flulike symptoms as a side effect at the a= 0.01 level of significance? Because npo (1-Po) = 15 10, the sample size is less than 5% of the population the requirements for testing the size, and the sample can be reasonably assumed to be random, hypothesis are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: P = 0.018 0.018 versus H₁: p (Type integers or decimals. Do not round.) Find the test statistic, Zo- (Round to two decimal places as needed.) Find the P-value. P-value= (Round to three decimal places as needed.) Choose the correct conclusion below. O A. Since P-value > a, do not reject the null hypothesis and conclude that there is not sufficient evidence that more than 1.8% of the users experience flulike symptoms. O B. Since P-value a, reject the null hypothesis and conclude that there is not sufficient evidence that more than 1.8% of the users experience flulike symptoms. O D.
