Use two decimal digits in your answers. Q65. 2-14 451.82 (e) (3pts) What is the predicted amount of international revenue for a movie that generated 162 million dollars in the US? 430O (d) Kung Fu Panda s m 162 dellars in ue us and 61l million dollars internationally. What is Kung Fs Panda 2's residual? )what percentage of variability in international revenue can be explained by US revomuc? (c)

y = -64.34 + (2.34 * 162) = 314.74.

Part d

.Residual = 614 - 314.74 = $299.26.

Part e

This is given by R-square value.

R2 = 0.769*0.769 = 0.5914.

Thus 59.14% variation is explained.

Thanks.
