Data was collected regarding the weight of a male white laboratory rat for the first 25 weeks after its birth. A scatterplot of the rat’s weight (in grams) and the time since birth (in weeks) indicates a fairly strong, positive linear relationship. The linear regression equation = 100 + 40 (where W = weight in grams and t = number of weeks since birth) models the data fairly well.
A. The weight of the rat increases by approximately 40 grams every week since birth.
B. The weight of the rat increases by approximately 1 gram every 40 weeks since birth.
C. The weight of the rat increases by approximately 140 grams every week since birth.
D. The weight of the rat increases by approximately 100 grams every week since birth.
