Determine how various attributes impact the purchase of a car. There are four attributes, each with three levels.
• Brand: Ford = 0, Chrysler = 1, GM =2
• MPG: 15 MPG = 0, 20 MPG = 1, 25 MPG = 2
Horsepower (HP): 100 HP = 0, 150 HP = 1, 200 HP = 2
• Price: $18,000 = 0, $21,000 = 1, $24,000 = 2
The nine product profiles ranked below were evaluated by a consumer: (note - the table should be reproduced using the dummy variables)

The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, and streams. Water samples were taken at four different locations in a river in an effort to determine if water pollution varied from location to location. Location I was 500 meters above an industrial plant water discharge point and near the shore. Location II was 200 meters above the discharge point and in midstream. Location III was 50 meters downstream from the discharge point and near the shore. Location IV was 200 meters downstream from the discharge point and in midstream. The following table shows the results. Lower dissolved oxygen readings mean more pollution. Because of the difficulty in getting midstream samples, ecology students collecting the data had fewer of these samples. Use a 5% level of significance. Do we reject or not reject the claim that the quantity of dissolved oxygen does not vary from one location to another?

The data file contains four taste evaluations. The taste evaluations were measured on a scale from 1 to 10 (with 10 the highest evaluation). Brand equity of one brand for one respondent is the difference of branded score and unbranded score of that brand evaluated by the respondent.
