A certain drug is used to treat asthma. In a clinical trial of the drug, 24 of 267 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. 1-PropZTest prop <0.09 2= - 0.006415399 p= 0.4974406436 p= 0.0898876404 n= 267 a.

d. What is the null hypothesis, and what do you conclude about it? Identify the null hypothesis. O A. Ho: p<0.09 О В. Но: р#0.09 ОС. Но: р> 0.09 O D. Ho: p= 0.09 Decide whether to reject the null hypothesis. Choose the correct answer below. O A. Reject the null hypothesis because the P-value is less than or equal to 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. Reject the null hypothesis because the P-value is greater than the significance level, a. O D. Fail to reject the null hypothesis because the P-value is greater than the significance level, a. e. What is the final conclusion? O A. There is not sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches. O B. There is sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches.
