In a clinical trial, 20 out of 600 patients taking a prescription drug complained of flulike symptoms. Suppose that it is known that 5.5% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that less than 5% of this drug's users experience flulike symptoms as a side effect at the α=0.04 level of significance?
