Transcribed Image Text:In a clinical trial, 19 out of 878 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 1.9% 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?
Họ:
versus H1:
(Type integers or decimals. Do not round.)
Find the test statistic, zo.
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.
Transcribed Image Text:Choose the correct conclusion below.
A. Since P-value > a, do not reject the null hypothesis and conclude that there is not sufficient evidence that more than 1.9% of the users experience flulike symptoms.
B. Since P-value > a, reject the null hypothesis and conclude that there is not sufficient evidence that more than 1.9% 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 1.9% of the users experience flulike symptoms.
O D. Since P-value < a, do not reject the null hypothesis and conclude that there is sufficient evidence that more than 1.9% of the users experience flulike symptoms.
