Use the following to answer the questions below:

While many people count calories, some often don't think about calories in the beverages they consume. Starbucks, one of the leading coffeehouse chains, provides nutrition information about all of their beverages on their website. Nutrition information, including number of calories, fat (g), carbohydrates (g), and protein (g), was collected on a random sample of Starbucks' 16 ounce ("Grande") hot espresso drinks. Note that all of the drinks in the sample are made with 2% milk unless the name specifically included the term "Skinny," which is how Starbucks indicated a beverage made with nonfat milk.

The regression equation is
Calories = 6.7 + 9.61 Fat (g) + 3.43 Carbs (g) + 4.42 Protein (g)

 Predictor Coef SE Coef T P
 Constant 6.68 17.64 0.38 0.715
 Fat (g) 9.609 1.452 6.62 0
 Carbs (g) 3.435 0.3155 10.89 0
 Protein (g) 4.418 2.231 1.98 0.083

S = 13.2293        R-Sq = 98.8%        R-Sq(adj) = 98.4%

Analysis of Variance

 Source DF SS MS F P
 Regression 3 116867 38956 222.58 0
 Residual Error 8 1400 175
 Total 11 118267

Is the model effective according to the ANOVA test? Use a 5% significance level. Include all details of the test.
