Breakfast cereal: ASSESS/USE. The regression model in Exercise 3.6 was fit to a sample of 36 breakfast cereals with calories per serving as the response variable. The two predictors were grams of sugar per serving and grams of fiber per serving. The partition of the sums of squares for this model is
SSTotal=SSModel+SSE
17190=9350+7840
-
Calculate R2 for this model and interpret the value in the context of this setting.
-
Calculate the regression standard error of this multiple regression model.
-
Calculate the F-ratio for testing the null hypothesis that neither sugar nor fiber is related to the calorie content of cereals.
-
Assuming the regression conditions hold, the P-value for the F-ratio in (c) is about 0.000002. Interpret what this tells you about the variables in this situation.

3.3 Breakfast cereals. A regression model was fit to a sample of breakfast cereals. The response variable Y is calories per serving. The predictor variables are X1, grams of sugar per serving, and X2, grams of fiber per serving. The fitted regression model is Y 109.3 +1.0.Xi -3.7 X2 In the context of this setting, interpret -3.7, the coefficient of X2. That is, describe how fiber is related to calories per serving, in the presence of the sugar variable.

Use the cereal label below to determine (a) the number of calories derived from carbohydrates; (b) the percentage of calories derived from sugar. Which of the cereal's nutrient contributions are increased by adding milk? Explain why cereal with milk has a higher carbohydrate value than cereal alone. Is this cereal predominantly starch or sucrose? Do starches and complex carbohydrates increase with the addition of milk? Calculate the caloric requirement of a 4-year old child who weighs 42 pounds. Determine the...
