Question

Many amusement parks base their projections of revenues and profits on the assumption that the average

young adult visits an amusement park four times per year. To investigate the validity of this assumption, a random sample of

63 young adults is drawn and each is asked to report the number of times they skied the previous year. The sample yields an average of 4.841 and a sample standard deviation of 2, can we infer that the assumption is wrong with 97% confidence?
