Question

What can predict how much a motion picture will make? The statistics computed below use data from a number of recent releases that includes the USGross (in S), the Budget ($), the Run Time (minutes), and the average number of stars awarded by reviewers.

What does it mean? Choose the correct explanation of R2 below, and fill in your calculated value of R2 A. Accounting for the number of predictors, about of the variation in USGross is accounted for by the least squares regression on Budget, Run Time, and Stars. O B. The probability that USGross is greater than the least squares regression on Budget, Run Time, and Stars is OC. The least squares regression on Budget, Run Time, and Stars will accurately predict USGross of the time. D. About of the variation in USGross is accounted for by the least squares regression on Budget, Run Time, and Stars. b) Why is the "Adjusted R Square" in the table different from the "R Square"? O A. Adjusted R2 accounts for the number of predictors, so it differs from R2, which does not. B. Adjusted R2 uses only the significant predictors with small P-values, so it differs from R2. which does not. O C. Adjusted R2 does not account for the number of predictors, so it differs from R2, which does. Adjusted R2 excludes the predictors with small P-values, so it differs from R2, which does not. D.
