Estimate the level of DVD sales (measured in million dollars) for movies, by using the amount of annual revenue (measured in million dollars) gener- ated by the box office gross. We randomly selected a sample of 43 movies for the same year. Excel (for a = 0.05) printed out: 72 = 0.5123, Sy x = 12.2279, critical = 2.0195, him = 0.026249, bo = 4.8445, bj = 0.1631. Assume normality and homoscedasticity are satisfied. Source f Sum of Squares Mean Squares F stat p - value F crit Regression 6439.6133 ?
