Researchers selected 831 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial, 18 out of the 831 patients complained of flulike symptoms. Suppose that it is known that \( 1.9 \% \) of patients taking competing drugs compla 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 \( \alpha=0.05 \) level of significance? \( \mathrm{H}_{0}: \mathrm{p}=0.019 \) versus \( \mathrm{H}_{1}: \quad \mathrm{p} \) (Type integers or decimals. Do not round.) Find the test statistic, \( z_{0} \). \( z_{0}=0.57 \) (Round to two decimal places as needed.) Find the P-value. P-value = \( \square \) (Round to three decimal places as needed.)
