In a clinical trial,18 out of 828 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 1.7% 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 α=0.1 level of significance?
