A certain drug is used to treat asthma. In a clinical trial of the drug, 24 of 281 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 11% 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 <0.11 z--1.3174 48179 p-0.0938442202 p-0.0854092527 n-281 a. is the test two-tailed, left-tailed, or right-tailed?
