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 50 43 Car Intermediate 57 44 Full-sized 61 45 Use a = 0.05 to test for any significant differences. State the null and alternative hypotheses. O Ho: HCompact * MIntermediate * /Full-sized Ha: MCompact = HIntermediate = Full-sized O Ho: MCompact = MIntermediate = /Full-sized Ha: MCompact * MIntermediate * /Full-sized O Ho: HComputerized = MElectronic = /Compact = MIntermediate = MFull-sized Ha: Not all the population means are equal. O Ho: HComputerized = MElectronic Ha: MComputerized * MElectronic O Ho: HComputerized * HElectronic Ha: HComputerized = HElectronic Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) D-value = State your conclusion. Do not reject Ho. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers. Type here to search Ri e W X 3:43 PM 2/23/2020 hp
