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. Analyzer Computerized Electronic Compact 51 43 Car Intermediate 55 44 Full-sized 62 45 Use a = 0.05 to test for any significant differences. State the null and alternative hypotheses.

O Reject Ho. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers. O Do not reject Ho. There is not sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers. O Reject Ho. There is not sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers. O Do not reject Ho. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers
