The following complete 2nd-order model is proposed to estimate the sales price of a single family home on the size of the house (x-) and the neighbourhood is located in (x2): E(y) = Bo + B1x1 + B2x1 + B3x2 + B4x1x2 + B5x1²x2. What hypotlesis should be tested to determine if the quadratic terms are necessary to predict the sales price of 2 %3D a home?

Question
The following complete 2nd-order model is proposed to estimate the sales price of a
single family home on the size of the house (x1) and the neighbourhood is located in
(x2): E(y) = Bo + B1x1 + B2x12 + B3x2 + B4x1x2 + B5x12x2. What hypothesis should be
tested to determine if the quadratic terms are necessary to predict the sales price of
a home?
