Researchers selected 897 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial, 21 out of tNOkt question plained of flulike symptoms. Suppose that it is known that 1.8% of patients laking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 1.8% of this drug's users experience flulike symptoms as a side effect at the a=0.1 level of significance?

Transcribed Image Text:Researchers selected 897 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial, 21 out of tNext question plained of flulike symptoms. Suppose that it is known that 1.8% of patients taking
competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 1.8% of this drug's users experience flulike symptoms as a side effect at the a= 0.1 level of significance?
satisfied.
Because npo (1- Po):
5% of the population size, and the patients in the sample
selected at random, all of the requirements for testing the hypothesis
10, the sample size is
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
Ho: P
0.018 versus H:
0.018
>
(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.)
Interpret the results.
Since the P-value is greater than a, do not reject the null hypothesis. There is not sufficient evidence at the a=
level of significance to conclude that more than
1.8 % of the users who take the prescription drug daily complained of
flulike symptoms.
