A certain drug is used to treat asthma. In a clinical trial of the drug, 18 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 0.05 significance level. What is the final conclusion? A. There is sufficient evidence support the claim that less than 11% of treated subjects experienced headaches. B. There is not sufficient evidence to warrant rejection of the claim that less than 11% of treated subjects experienced headaches. C. There is not sufficient evidence support the claim that less than 11% of treated subjects experienced headaches. D.
