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 63 56 72 74 68 65 75 69 77 66 58 78 73 59 73 70 63 Use = 0.05 and test to see whether there is a significant difference in the time required by the three methods.
