A certain drug is used to treat asthma. In a clinical trial of the drug, 21 of 256 treated subjects experienced than 9% of treated subjects experienced headaches use the normal an bution as an approxirmation to the binomial distribution and assume a 0.05 significance level to complete parts (a) thr ОА, НО p>009 O B. Hop009 O C. Ho p-009 Decide o A. whether to reject the null hypothesis. Choose the correct answer below Rejed the nut hypothesis because the P-value is greater than the significance level, α B. Fail to reject the nul hypothesis because the P-value is greater than the sgrificance level c. Reject the nua hypothesis because the p.value is less than or equal to the D. Fail to reject the null hypothesis because the P.value is less than or equal to the significance level, a There is sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects There is sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches There is not suf cient evidence to support the claim that less than 9% of treated subjects experienced headaches.
