K A certain drug is used to treat asthma. In a clinical trial of the drug, 21 of 264 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 8% 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. a. Is the test two-tailed, left-tailed, or right-tailed? O Right tailed test O Left-tailed test Two-tailed test O CELEB 1-PropZTest prop<0.08 z=-0.027223275 p=0.4891408259 p=0.0795454545 n=264
