Question 1: What is a control variable in a regression model?

1) the "cause variable" of interest in a study

2) the coefficient on a regressor

3) the dependent variable

4) a regressor included to eliminate omitted variable bias

----------------------------------------------------------------------------------------------

Question 2: What is the base specification in a regression analysis?

1) the simplest specification that includes only one regressor

2) the regression including only control variables as regressors

3) the most complex regression specification you can think of

4) the regression including a core set of regressors, including the variables of primary interest and control variables suggested by theory and/or expert judgement

You are selling two goods, 1 and 2, to a market consisting of three

consumers with reservation prices as follows:

Consumer    For 1                 For 2

A               20                                4

B                 12                            12

C                  4                               20

The unit cost of each product is $6.

Compute the optimal prices and profits for

(i) selling the goods separately,

(ii) pure bundling, and

(iii) mixed bundling.

                               Price 1 Price 2 Bundled Price Profit

Sell Separately     $20        $20           —               $28

Pure Bundling         —          —             $24            $36

Mixed Bundling      $19        $19         $24             $38 ???????Why MIxed bunding is 19? ?????? how do you get 19???????

Complete the statements correctly.

A chance experiment is an experiment where 1) The result is not predetermined 2) The result is predetermine 3) The result is either zero or one,

such as 1) Getting tails when flipping a coin 2) Selecting a card from a deck to see what suit you get 3) Deciding which cereal to buy at the store.

An outcome is 1) The result of one instance of an experiment 2) The probability of one result of an experiment 3) The conclusion drawn about an experiment 4) A type of chance experiment.

The sample space for an experiment is the 1) Population from which the sample is chosen 2) Combination of any number of outcomes 3) Sample of participants used to run the experiment 4) Set of all potential results of the experiment.

A real estate developer wishes to study the relationship between the size of home a client will purchase (in square feet) and other variables. Possible independent variables include the family income, family size, whether there is a senior adult parent living with the family (1 for yes, 0 for no), and the total years of education beyond high school for the husband and wife. The sample information is reported below.

Family Square Feet Income (000s) Family Size Senior Parent Education

2 2,300 68.4 2 1 6

9 4,200 133 5 0 2
10 2,800 95 3 0 6
  1. Develop an appropriate multiple regression equation using stepwise regression. (Use Excel data analysis and enter number of family members first, then their income and delete any insignificant variables. Leave no cells blank - be certain to enter "0" wherever required. R and R2 adj are in percent values. Round your answers to 3 decimal places.)
