Find z0 and the P-value

Researchers selected 878 patients at random among those who take a certain widely-used prescription drug daily. In a clinical trial, 17 out of the 878 patients
complained of flulike symptoms. Suppose that it is known that 1.5% of patients taking competing drugs complain of flulike symptoms. Is there sufficient
evidence to conclude that more than 1.5% of this drug's users experience flulike symptoms as a side effect at the α = 0.1 level of significance?
Because npo (1-Po) = 13.0 > 10, the sample size is
random, all of the requirements for testing the hypothesis
