The output below is from a medical study that used multiple linear regression analysis to link monthly changes in weight (y = weight change in ounces) to daily exercise (x1 = minutes of strenuous daily exercise) and daily fat calorie intake (x2 = number of fat calories consumed daily). The sample consisted of 28 men in the 25-to-35-year age group.
a. Identify and interpret the estimated regression coefficients for x1 and x2.
b. Fill in the values of SSR and SSE.
c. Show that the standard error of estimate is equal to the square root of SSE/(n – k –1), where n number of observations and k number of independent variables.
