Transcribed Image Text:certain drug is used to treat asthma. In a clinical trial of the drug, 16 of 265 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
approximation to the binomial distribution and assume a 0.05 significance level to complete parts (a) through (e) below.
a. Is the test two-tailed, left-tailed, or right-tailed?
O Right tailed test
