Question

Suppose a study reported that the average person watched 5.20 hours of television per day. A random sample of 15 people gave the number of hours of television watched per day shown. At the 1% significance level, do the data provide sufficient evidence to conclude that the amount of television watched per day last year by the average person differed from the value reported in the study?
