- (t-Distribution) A study conducted a few years ago claims that adult males spend an
average of 11 hours a week watching sports on television. A recent sample of 100
adult males showed that the mean time they spend per week watching sports on
television is 9.50 hours with a standard deviation of 2.2 hours. Test at the 5%
significance level if currently, all adult males spend less than 11 hours watching
sports on television.
