The national football league has performed a study in which the total yards gained by teams in games was used as an independent variable to explain the variation in total points scored by teams during games. the points scored ranged from 0 to 57 and the yards gained ranged from 187 to 569. the following regression model was determined: = 12.3 + .12x. given this model, which of the following statements is true?
a. for every one point scored, the predicted number of yards gained increased by 0.12, on average.
b. for every one yard gained, the predicted number of points increased by 0.12, on average.
c. for every one yard gained, the predicted number of points scored decreased by 12.3, on average.
d. for every one point scored, the predicted number of points scored, decreased by 12.3, on average.
