A certain drug is used to treat asthma. In a clinical trial of the drug, 18 of 268 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a 1-Prop2Test test of the claim that less than 9% of treated subjects experienced headaches.

Mat 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) Experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a through (e) below. Identify the null hypothesis. O A. Ho: p#0.09 O B. Ho: p>0.09 O C. Ho: p<0.09 O D. Ho: p=0.09 Decide whether to reject the null hypothesis. Choose the correct answer below. O A. Fail to reject the null hypothesis because the P-value is greater than the significance level, a. B. Reject the null hypothesis because the P-value is greater than the significance level, a. O C. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a. 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 not sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches. O B. There is sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects experienced headaches. C. There is sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches. O D. There is not sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects experienced headaches. Click to select your answer(s).
