Write the hypotheses for a paired-samples t test for Exercise 9.38.

Data from exercise 9.38

Elementary school teachers who did and did not have children of their own were matched in terms of the number of years of experience they had teaching. They were then asked how many minutes of homework a child should complete per night. The researcher planned to use a paired-samples t test to determine if having children of one’s own were related to this response. Based on the assumptions for the test, is it OK to proceed?
