6. [-14 Points] DETAILS ASWSBE14 18.E.043. MY NOTES ASK YOU You may need to use the appropriate technology to answer this question. A client wants to determine whether there is a significant difference in the time required to complete a program evaluation with the three different methods that are in common use. Suppose the times in hours) required for each of 18 evaluators to conduct a program evaluation follow. Method 1 Method 2 Method 3 66 62 56 71 73 65 68 78 69 77 66 55 75 72 59 72 70 62 Use a = 0.05 and test to see whether there is a significant difference in the time required by the three methods. = State the null and alternative hypotheses. Ho: Not all populations of times are identical. Ha: All populations of times are identical. Ho: Median 1 = Median2 = Median3 Ha: Median 1 Median2 Median3 Ho: Median 1 = Median 2 = Median3 Ha: Median 1 > Median2 > Median3 Ho: Median 1 Median2 + Median3 Ha: Median 1 = Median2 = Median3 Ho: All populations of times are identical. Ha: Not all populations of times identical. 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. Reject Ho. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Reject Ho. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods.
