The average person spends 5.1 hours a day watching television. A
recent sample of 38 people revealed that they spend an average of
4.2 hours a day watching television. The population standard
deviation of the number of hours spent watching television is 1.8
hours. Using a 0.10 level of significance, can it be concluded that
the average American spends less than 5.1 hours a day watching
television? Show your work to receive credit.

According to a certain survey, adults spend 2.25 hours per day
watching television on a weekday. Assume that the standard
deviation for "time spent watching television on a weekday" is
