Teresa was researching sales figures for popular video games. She wondered if she could predict a game's
global sales based on its sales in North America. She noticed a positive linear relationship between North
America sales and global sales (both in millions) in a random sample of games. Here is a least-squares
regression analysis of her data:
Predictor
Coef SE Coef
T
P
Constant
0.744
0.831
0.895 0.375
North America
0.497
0.037 13.610 0.000
S = 3.119
R-sq = 79.4%
Which of these is an appropriate least-squares equation for this model?
Choose 1
global = 0.831 + 0.037(North America)
Ð’
global = 0.744 +0.497(North America)
global = 0.744 +0.831(North America)
global = 0.497 + 0.037(North America)
