A certain drug is used to treat asthma. In a clinical trial of the drug, 16 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 10% 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 <0.1 z = -2.374781216 p=0.0087796774 p=0.0573476703 n=279

b. What is the test statistic? Z= (Round to two decimal places as needed.) c. What is the P-value? P-value= (Round to four decimal places as needed.) d. What is the null hypothesis, and what do you conclude about it? Identify the null hypothesis. OA. Ho: p *0.08 OB. Ho: p=0.08 Oc. Ho:p> 0.08 OD. Ho: p<0.08 Decide whether to reject the null hypothesis. Choose the correct answer below. OA. Reject the null hypothesis because the P-value is greater than the significance level, a. OB. 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.. OD. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a.
