Hours of Television Viewing

Data on the text's website show the number of hours per week of television viewing for random samples of fifth grade boys and fifth grade girls.

Each student logged his or her hours for one Monday-through-Friday period.

Assume that the students were independent; for example, there were no pairs of siblings who watched the same shows.

Using graphical and numerical summaries, write a brief description of how the hours differed for the boys and girls.

Then carry out a hypothesis test to determine whether the mean hours of television viewing are different for boys and girls.

Evaluate whether the conditions for a t-test are met, and state any assumptions you must make in order to carry out a t-test.
