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 50 41 Car Intermediate 57 44 Full-sized 61 47 Use a = 0.05 to test for any significant differences. State the null and alternative hypotheses.

(Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value =
