Question

In a clinical trial, 18 out of 840 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 1.8% of patients taking competing drugs complain of Puike symptoms. Is there sufficient evidence to conclude that more than 1.8% of this drug's users experience fiulike symptoms as a side effect at the a= 0.05 level of significance? Because np. (1-P) O10, 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 H, (Type Integers or decimals. Do not round) Find the test tisti, 20 70 (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,reject the null hypothesis and conclude that there is not sufficient evidence that more than 18% of the users experience flulike symptoms. OB. Since P-value <a, reject the nut hypothesis and conclude that there is sufficient evidence that more than 1.8% of the users experience flulike symptoms. einen mind the sheen that there and that when there were made Click to select your answer(s).
