A certain drug is used to treat asthma. In a clinical trial of the drug, 27 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 11% 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.
