certain drug is used to treat asthma. In a clinical trial of the drug, 18 of 266 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 9% 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 parts (a) through (e) below. Is the test two-tailed, left-tailed, or right-tailed? What is the test statistic? What is the P-value? What is the null hypothesis, and what do you conclude about it? Decide whether to reject the null hypothesis. Choose the correct answer below.
