A certain drug is used to treat asthma. In a clinical trial of the drug, 27 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 9% of treated 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. 1-Prop2Test prop <0.09. z-0.395382781 p-0.6537197926 p-0.0967741935 n-279 Decide whether to reject the null hypothesis. Choose the correct answer below. O A. Reject the null hypothesis because the P-value is greater than the significance level, a. O B. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a. OC. Fail to reject the null hypothesis because the P-value is greater than the significance level, a. O D. Reject the null hypothesis because the P-value is less than or equal to the significance level, a. e. What is the final conclusion? O A. There is sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects experienced headaches. O B. There is not sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches. O C. There is sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches. OD. There is not sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects experienced headaches.
