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 were used as blocks in the experiment. The data obtained follow. Analyzer Computerized Electronic Compact 49 41 Car Intermediate 55 44 Full-sized 64 47 Use a = 0.05 to test for any significant differences. State the null and alternative hypotheses. Ho: " Computerized Electronic Compact Intermediate Full-sized H. : Not all the population means are equal. O Ho: H Computerized # Electronic Hai /Computerized - HElectronic O Ho: "compact * HIntermediate * HFull-sized Ha: "Compact Intermediate Full-sized O Ho: HComputerized Electronic Ha: HComputerized * HElectronic O Ho: HCompact = HIntermediate - HFull-sized Ha: "Compact * #Intermediate * Full-sized 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. 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 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. O Do not reject Ho. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers
