In a clinical trial, 22 out of 832 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.3 % of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.3% of this drug's users experience flulike symptoms as a side effect at the alpha equals 0.05α= level of significance?
What are the null and alternative hypotheses?
Find the test statistic z 0z0.
Find the P-value.
A. Since P-valuegreater thanalpha, do not reject the null hypothesis and conclude that there is not sufficient evidence that more than 2.3% of the users experience flulike symptoms.
B. Since P-valueless thanalpha, reject the null hypothesis and conclude that there is sufficient evidence that more than 2.3% of the users experience flulike symptoms.
C. Since P-valueless thanalpha, do not reject the null hypothesis and conclude that there is sufficient evidence that more than 2.3% of the users experience flulike symptoms.
D. Since P-valuegreater thanalpha, reject the null hypothesis and conclude that there is not sufficient evidence that more than 2.3% of the users experience flulike symptoms.
