Question

A regression analysis was performed to determine which, if any, of protein (grams), total fat (grams), fiber (grams), carbohydrates (grams), and sugars (grams) are associated with calories in a sample of 34 breakfast cereals. An F-test is to be performed. How many degrees of freedom does the F-statistic have? Choose the correct answer below. A. numerator = 3, denominator = 30 B. numerator = 1, denominator = 32 C. numerator = 3, denominator = 31 D. numerator = 5, denominator = 28 E. numerator = 4, denominator = 30

Explanation / Answer

here numerator degree of freedom =p=independent variable =5

and denomiantor degree of freedom=n-p-1=34-5-1=28

hence option D is correct
