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 69 64 59 72 71 68 65 75 66 77 69 58 78 74 56 74 70 64 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. OH : Not all populations of times are identical. H : All populations of times are identical. Ho: Median, + Median, + Median, H: Median = Median, - Median O Ho: Median, = Median2 = Median Ho: Median, + Median, + Median, O Ho: Median, = Medianz = Median, H: Median, > Median, > Medianz O Ho: All populations of times are identical. H: Not all populations of times are 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.) D-value = State your conclusion. O Reject Ho. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Reject H. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Do not reject H. 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.
