A certain drug is used to treat asthma. In a clinical trial of the​ drug, 17 of 298 treated subjects experienced headaches​ (based on data from the​ manufacturer). The accompanying calculator display shows results from a test of the claim that less than 88​% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.05 significance level to complete.

What is the test statistics?

z=_ (round to two decimal places as needed.)

What is the P-value?
