In 2014, the General Social Survey asked about the number of hours a week spent on the World Wide Web, not counting e-mail. The 778 females had a mean of 11.2 and standard deviation of 13.7.

The 620 males had a mean of 11.9 and standard deviation of 16.0.

Use these results to make an inference comparing males and females in the population. Since the sample standard deviations are not dramatically different, your inference can assume equality of population standard deviations.
