Refer to Problem 16.123 and its accompanying data file.  Please read this question carefully as content of the test question may be different than in your textbook.  Some critics of television complain that the amount of violence shown on television contributes to violence in our society. Others point out that television also contributes to the high level of obesity among children. We may have to add financial problems to the list. A sociologist theorized that people who watch television frequently are exposed to many commercials, which in turn leads them to buy more, finally resulting in increasing debt. To test this belief, a sample of 430 families was drawn. For each, the total debt and the number of hours the television is turned on per week were recorded. 

Perform a linear regression of y on x to help test the theory that we can predict family financial debt from the number of hours the television is turned on.
