Question

A popular board game manufacturer was interested in the relationship between the amount of time it takes to play a game and how well that game is rated among board game players. Information was collected on several board games, and was used to obtain the regression equation y = 27.273x + 18.182, where x represents time it takes to play (in hours) and y is the predicted rating of that game (in points). What is the predicted rating of a game that takes 90 minutes to play?

18.182 points
59.0915 points
90 points
2,472.752 points

Answer 1

The answer is B. I don't know why everyone downvoted the first answer. So here's some fancy work so you know its right.

90 minutes/1 hour = 1.5 hours [one hour = 60 minutes]

(you can only put hours in for x)

27.273(1.5) + 18.182 = 59.0915 (B)
