For the 20 top-grossing U.S. films of the 1990s, data have been reported for y = foreign gross ticket sales and x = domestic gross ticket sales, both in millions of dollars. The printout here shows the results for a second order polynomial model fitted to the data. What amount of foreign gross ticket sales would be predicted for a film that generated $400 million in domestic gross ticket sales? At the 0.05 level of significance, is this model significant?
