12.10 Compute the coefficients b1 and b2 for the regression model yn i = b0 + b1x1i + b2x2i given the following summary statistics.

a. rx1y = 0.80, rx2y = 0.30, rx1x2 = 0.90, sx1 = 500, sx2 = 400, sy = 100

b. rx1y = -0.80, rx2y = -0.30, rx1x2 = 0.90, sx1 = 500, sx2 = 400, sy = 100

c. rx1y = 0.40, rx2y = 0.75, rx1x2 = 0.90, sx1 = 500, sx2 = 400, sy = 100

d. rx1y = 0.80, rx2y = -0.40, rx1x2 = -0.10, sx1 = 500, sx2 = 400, sy = 100 Application Exercises
