Question
A certain drug is used to treat asthma. In a clinical trial of the drug, 29 of 274 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 12% 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. 1-PropZTest prop<0.12 z = 0.721314205 p=0.2353581096 ^ p= 0.1058394161 n = 274 a. Is the test two-tailed, left-tailed, or right-tailed? Two-tailed test Left-tailed test Right tailed test b. What is the test statistic? Z= (Round to two decimal places as needed.) c. What is the P-value? P-value = (Round to four decimal places as needed.)
