A certain drug is used to treat asthma. In a clinical trial ofthe drug, 16 of 279 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 11% oftreated subjects experienced headaches use the normal distribution as an approximation to the binomial distribution and assume a 0.01 significance level to complete parts (a) through (e) below. a. Is the test two-tailed, left-tailed, or right-tailed? C) Right tailed test C) Left-tailed test C) Two-tailed test b. What is the test statistic7 (Round to two decimal places as needed) c. What is the P-value? P-value = (Round to four decimal places as needed.) d. What is the null hypothesis, and what do pu conclude about it? Identify the null hypothesis. OB. OC. Decide whether to reject the null hypothesis. Choose the correct answer below. C) A. Fail to reject the null hypothesis because the P-value is greater than the significance level, cr. C) B. Reject the null hypothesis because the P-value is greater than the significance level, a. C) C. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, cr. C) D. Reject the null hypothesis because the P-value is less than or equal to the significance level, u. e. What is the final conclusion?
