An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.:

Car
Compact Intermediate Full Size
Analyzer Computerized 50 55 63
Electronic 42 44 46

The following regression model can be used to analyze the data for a randomized block design involving two treatments and three blocks.

E(y) = 0 + 1x1 + 2x^2 + 3x^3
Show the values of the variables below.
