Question
In a clinical trial, 26 out of 896 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 = 0.01 level of significance?
Because npo (1- Po) =
10, 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 H1:
(Type integers or decimals. Do not round.)
Find the test statistic, zo.
Zo
(Round to two decimal places as needed.)
%3D
Find the P-value.
P-value =
(Round to three decimal places as needed.)
Choose the correct conclusion below.
A. 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.
B. 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.
C. 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.
D. 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.
