Question

A regression model between sales ( y in $1000), unit price ( x 1 in dollars), and television advertisement ( x 2 in dollars) resulted in the following function: y? = 7 - 3x1 + 5x2 For this model, SSR = 3500, SSE = 1500, and the sample size is 18. The adjusted multiple coefficient of determination for this problem is a. .8367. b. .66. c. .70. d. .2289.

Step 1

We can do this using the formula: R^2 = SSR / (SSR + SSE) Where SSR is the sum of squares due to regression, and SSE is the sum of squares due to error. Given SSR = 3500 and SSE = 1500, we can calculate R^2: R^2 = 3500 / (3500 + 1500) = 3500 / 5000 = 0.7 Now, Show more…
