Consider the following time series data. Week 1 2 3 4 5 un 6 3 16 Value 17 13 11 17 الما Using the naive method (most recent value) as the forecast for the next week, compute the following measures of forecast accuracy (a) mean absolute error MAE = (b) mean squared error MSE (c) mean absolute percentage error (Round your answer to two decimal places.) MAPE = % (d) What is the forecast for week 72

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 64 56 72 71 65 67 77 69 78 66 55 75 74 59 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. O Ho: Not all populations of times are identical Ho: All populations of times are identical. O Ho: All populations of times are identical H: Not all populations of times are identical Ho: Median, Median, Mediany Ho Median, - Mediana - Median O No Median, - Median, - Median M Median, > Median, > Median O Ho: Median - Median, - Median Ha: Median, Median Median

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 sufficient evidence to conclude that there is a significant difference in the time required by the three methods O Reject Ho. 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 Ho. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. O 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.
