Suppose that you have estimated coefficients for the following regression model:

Y = b0 + b1X1 + b2X2 + b3X3 Test the hypothesis that all three of the predictor variables are equal to 0, given the following analysis of variance table.

a. Analysis of variance 1a = 0.052 Source DF SS MS Regression 3 3,000 Residual Error 25 500

b. Analysis of variance 1a = 0.052 Source DF SS MS Regression 3 4,500 Residual Error 21 500

c. Analysis of variance 1a = 0.052 Source DF SS MS Regression 3 42,000 Residual Error 30 27,000

d. Analysis of variance 1a = 0.012 Source DF SS MS Regression 3 9,606 Residual Error 21 2,300
