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.



Which number on the screen represents the estimator of  β2?
◦ 5.5
◦ 11
◦ .9286
◦ .9405

Did you know?

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
