Write the hypotheses for a paired-samples t test for Exercise 9.37.

Data from exercise 9.37

A group of high school students were in the same math, English, social studies, and science classes. A researcher monitored how much time, during a week, they spent online in school activities (doing homework) vs. how much time they spent online in social activities (on Facebook, chatting, playing multiplayer games). The researcher planned to use a  aired-samples t test to analyze the data to see if there was a difference in time spent on the two activities. Based on the assumptions, is it OK to proceed with the test.
