Question

Interpret the estimates b1 and b2.

The following model was fitted to a sample of 30 families in order to explain household milk
consumption:
y = Bo + B1x1i + B2x2i + Ei
where
y = milk consumption, in quarts per week
x1 = weekly income, in hundreds of dollars
X2 = family size
The least squares estimates of the regression parameters were as follows:
bo = -0.025
bi = 0.052
b2 = 1.14
%3D
|3D
The total sum of squares and regression sum of squares were found to be as follows:
SST = 162.1 and SSR = 88.2
