In a regression analysis involving observations, the following estimated regression equation was obtained. Enter negative values as negative numbers. ŷ= 17.6 + 3.8x1 - 2.3x2 + 7.6 x3 + 2.7x4

Interpret b1,b2,b3 and b4 in this estimated regression equation. Assume that for each coefficient statement, the remaining three variables are held constant (to 1 decimal).

b1= estimated change in y per 1 unit change in xl
b2= estimated change in y per 1 unit change in x2
b3= estimated change in y per 1 unit change in x3
b4= estimated change in y per 1 unit change in x4

Required:
Predict y when x1 =10, x2= 5, x3 =1, and x4 =2 (to 1 decimal).
