Question 1

Which equation represents a complete second-order model for two quantitative independent variables?
◦ E(y) = β0 + β1x1 +  β2x2 +  β3 + β4
◦ E(y) = β0 + β1x1x2 +  β2 + β3
◦ E(y) = β0 + β1 + β2 +  β3x2 +  β4x1 + β5
◦ E(y) = β0 + β1x1 +  β2x2 +  β3x1x2 +  β4 + β5

Question 2

A graphing calculator was used to fit the model E(y) = β0 + β1x + β2x2 to a set of data. The resulting screen is shown below.
