Explanation / Answer

1b. b0 represents the weight when the circumference is 0 and b1 represents the change in weight for a unit change in circumference

1c. Predicted weight for pumpkin = -2629.22 + 82.47(50) = 1494.28

1d. The F value if found to be statistically significant indicates that the coefficients are simultaneously not equal to 0. Here, the F value in this case is statistically significant which means that b0 and b1 are simultaneously determining the weight.

1e. Coefficient of determination is nothing but R2 whose adjusted value is equal to 0.934 i.e 93.4% of the variation in weight are explained by the variation in circumference
