Question

regression equation: y= 10.7 + 2.5 railcars

so y intercept 10.667 and slope is 2.1495... std dev is 5.157
r-sq = 96.7%, r-sq (adj) = 96.3%
data table
number of railcars | fuel consumption (units/mi)
20 | 58
20 | 52
37 | 91
31 | 80
47 | 114
43 | 98
39 | 87
50 | 112
40 | 100
29 | 70

would it be reasonable to use the fitted regression equation to predict the fuel consumption for a train on this route if the train had 65 railcars?
