In a clinical trial,
24
out of
850
patients taking a prescription drug complained of flulike symptoms. Suppose that it is known that

%
of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than
1.7
%
of this drug's users experience flulike symptoms as a side effect at the
alpha equals 0.05
level of significance?

Explanation / Answer
We need to test the claim whether more than 17% of this drug's users experience flulike symptoms as a side effect or not. Hence,
Our null and alternative hypotheses will be:
Ho: p = 0.17
H1: p > 0.17
