A certain drug is used to treat asthma. In a clinical trial of the drug, 22 of 282 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 0.01 significance level to complete parts (a) through (e) below. 1-PropZTest prop <0.1 z = - 1.230682091 p= 0.1092208944 p= 0.0780141844 n = 282 ... U D. T10·p-u. С. Но: р<0.1 O D. Ho: p+0.1 Decide whether to reject the null hypothesis. Choose the correct answer below. O A.
