A large company that produces allergy medications claims that Americans lose an average of 40 hours of work to problems related to seasonal allergles. A consumer advocacy group believes that company's claim exhibits self-interest bias. In other words, the advocacy group believes that the actual mean number of missed hours is less than claimed. The advocacy group would like to obtain statistical evidence about this issue and takes a random sample of 100 American workers. They find that these 100 people lost and average of 38 hours due to seasonal allergy symptoms. The standard deviation is 9.5 hours. a) What are the correct null and alternative hypotheses in this situation? A) Ho: u = 40 vs. Hai p< 40 B) Ho: H = 40 vs. Ha: u# 40 C) Ho: u = 38 vs. Hai H< 38 D) Họ: µ = 38 vs. Ha: p 38
