Question: The following computer output is from fitting a regression model to the snake length data of Example 12.2.2. The regression equation is Weight = -301

The following computer output is from fitting a regression model to the snake length data of Example 12.2.2.
The regression equation is
Weight = -301 + 7.19 Length

s = 12.50 R-sq = 89.1% R-sq(adj) = 87.5%
