You may need to use the appropriate technology to answer this question. 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 types of cars were used as blocks in the experiment. The data obtained follow. Analyzer Computerized Electronic Compact 50 43 Car Intermediate 56 43 Full-sized 62 46 Use a = 0.05 to test for any significant differences. State the null and alternative hypotheses. Ho: "Compact # #Intermediate * /Full-sized Ha: "Compact = /Intermediate = /Full-sized O Ho: "Computerized = HElectronic Compact #Intermediate = /Full-sized Ha: Not all the population means are equal. O Ho: HCompact = /Intermediate = /Full-sized Ha: "Compact * #Intermediate * /Full-sized O Ho: Computerized = /Electronic Ha: Computerized * Electronic Ho: "Computerized # #Electronic Ha: Computerized = /Electronic 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.) p-value = State your conclusion. Do not reject Ho. There is not sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers. Reject Ho. There is not sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers. Reject Ho. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers. Do not reject Ho. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers
