Use computer software packages, such as Excel, to solve this problem. An automobile dealer conducted a test to determine whether the time 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 (time in minutes) obtained follow. Car Compact Intermediate Full Size Computerized 45 53 61 Analyzer Electronic 37 42 44 The following regression model can be used to analyze the data for a randomized block design involving two treatments and three blocks. If your answer is zero enter "0". E(y) = Bo + B1X1 + 82X2 + B3X3 Analyzer X 1 Computerized Electronic 1 Car X2 X3 Compact O 0 Intermediate O Full Size Show the estimated regression equation (to 1 decimal, if necessary). Enter negative value as negative number. y = X1+ X2 + X3 Use a = 0.05 to test for any significant differences. What is the value of the t test statistic for the type of analyzer (to 2 decimals)? Enter negative value as negative number. What is the p-value? - Select your answer - What is your conclusion? - Select your
