A brochure inviting subscriptions for a new diet program states that the participants are expected to lose over 27 pounds in five weeks. Suppose that, from the data of the five-week weight losses of 65 participants, the sample mean and sample standard deviation are found to be 21.5 and 3.4, respectively. Could the statement in the brochure be substantiated on the basis of these findings? Test at the α = .01 level. Give detailed explanation with solution.
