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 19 evaluatars to conduct a program evaluation follow. Method 1 Method 2 Method 3 68 64 58 72 71 69 GG 76 67 75 68 50 79 74 57 74 zn 64 Usc-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 : All populations of times are identical. 11: Not all populations of times are identical OH: Median, - Median, - Median W: Mecan = Median = Median, Mecan OHO: Median, - Medianz = Median H: Med an + MedianMed ang OHO: Median, - Medlanz - Medians H: Mecan, Mediana Median OH, Not all populations of times are identical. H: 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.) p-value State your condusion Eestor Reject H, There is sufficient evidence ta conclude that there is a significant difference in the time required by the three methods. Reject M. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods. O Do not reject W. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. O Do not reject it.
