a. The estimated intercept is .
b. The estimate coefficient of x1 is .
c. The estimated coefficient of x2 is .
d. The estimated coefficient of x3 is .
e. If x1 = 12, x2 = 5, and x3 = 10, the estimated value of y is .
f. If x3 were to increase by 4, the change that would be necessary in x2 in order for the estimated value of y to remain unchanged is . Required minimum-1 page
