We are interested in whether the cost of a slice of pizza is affected by Pie Weight, Fat/slice, and/or Calories/slice. Cost/Slice($)= Be + B Pie Weight+B, Fatslice + B,Calories + Suppose our residual analysis of the model above indicated the potential for non-linearity in the relationships between cost/slice and fat/slice. Suppose we ran the following model to investigate this: Cost/Slice($) = Be + B Ple Weight + B, Fat/slice + B, Fat/slice Sqr +8 The regression results are given in the table below.

A Interpret the effect of an additional 10 ounces of pie weight on the cost of slice of pizza: Interpret the effect of an additional gram of fat on the cost of a slice of pizza if we start with a pizza that has 7 grams of fat in a slice: (Enter answer out to two decimal places.) A Interpret the effect of an additional gram of fat on the cost of a slice of pizza if we start with a pizza that has 15 grams of fat in a slice: (Enter answer out to two decimal places.) 1 A/ Interpret the effect of an additional gram of fat on the cost of slice of pizza if we start with a pizza that has 27 grams of fat in a slice: (Enter answer out to two decimal places.)
