In a clinical trial,
23
out of
874
patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that
2.1%
of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than
2.1%
of this drug's users experience flulike symptoms as a side effect at the
α=0.01
level of significance?Because
sample size is
5% of the population size, and the sample
