In a clinical trial, 26 out of 889 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.5% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.5% of this drug's users experience flulike symptoms as a side effect at the a = 0.1 level of significance? Because npo (1- Po) = V10, the sample size is 5% of the population size, and the sample V the requirements for testing the hypothesis V 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 statistic, zo. Zo (Round to two decimal places as needed.)

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 2.5% of the users experience flulike symptoms.
B. Since P-value < a, reject the null hypothesis and conclude that there is sufficient evidence that more than 2.5% of the users experience flulike symptoms.
C. Since P-value < a, do not reject the null hypothesis and conclude that there is sufficient evidence that more than 2.5% of the users experience flulike
symptoms.
D. Since P-value > a, do not reject the null hypothesis and conclude that there is not sufficient evidence that more than 2.5% of the users experience flulike
symptoms.
