Researchers selected 849 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial, 21 out of the 849 patients complained of flulike symptoms. Suppose that it is known that 2.2% of
patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.2% of this drug's users experience flulike symptoms as a side effect at the x = 0.05 level of significance?
