A certain drug is used to treat asthma. In a clinical trial of the drug, 21 of 300 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-PropZTest prop <0.09 z- -1.210455065 p=0.1130521616 p-0.0700000000 n- 300

d. What is the null hypothesis, and what do you conclude about it? Identify the null hypothesis. Ho: p> 0.09 Ho: p=0.09 Ho: p#0.09 Ho: p<0.09 Decide whether to reject the null hypothesis. Choose the correct answer below. Reject the null hypothesis because the P-value is greater than the significance level, a. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a. Fail to reject the null hypothesis because the P-value is greater than the significance level, a.
