A certain drug is used to treat asthma. In a clinical trial of the drug, of 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 % of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a significance level to complete parts (a) through (e) below. 1-PropZTest prop z p n a. Is the test two-tailed, left-tailed, or right-tailed? Right tailed test Left-tailed test Your answer is correct. Two-tailed test b. What is the test statistic? z 1.79 (Round to two decimal places as needed.) c. What is the P-value?
