A dietician read in a survey that at least 60% of adults skip breakfast at least 3 days a week. To verify this, she selected a random sample of 80 adults and asked them how many days a week they skipped breakfast. 50 of the adults in the sample said they skipped breakfast at least 3 days a week. At a = 0.10, test the survey's claim. (To get full credit you must show all parts of the hypothesis test, including the conclusion you reach about the claim.)
