researchers selected 822 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial, 19 out of the 822 patients complained of flulike symptoms. Suppose that it is known that

1.9% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than

1.9% of this drug's users experience flulike symptoms as a side effect at the =0.1 level of significance?
