Question
A certain drug is used to treat asthma. In a clinical trial of the drug, 30 of 299 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. d. What is the null hypothesis, and what do you conclude about it? Identify the null hypothesis. O A. Ho: p0.12 B. Ho: p=0.12 C. Ho: p>0.12 D. Ho: p<0.12 1-PropZTest prop<0.12 z 1.046429014 p= 0.1476815015 p=0.1003344482 n = 299 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 less than or equal to the significance level, a. B. Reject the null hypothesis because the P-value is greater than the significance level, a. C. Reject the null hypothesis because the P-value is less than or equal to the significance level, a. D. Fail to reject the null hypothesis because the P-value is greater than the significance level, α. e. What is the final conclusion? A. There is not sufficient evidence to warrant rejection of the claim that less than 12% of treated subjects experienced headaches. B. There is sufficient evidence to warrant rejection of the claim that less than 12% of treated subjects experienced headaches. C. There is sufficient evidence to support the claim that less than 12% of treated subjects experienced headaches. D. There is not sufficient evidence to support the claim that less than 12% of treated subjects experienced headaches.
