Consider the following time series data. Using the nalve 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 7 ? 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. Use =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. H0:Median1=Median2=Median3Ha:Median1=Median2=Median3 H0: All populations of times are identical. Ha: Not all populations of times are identical. H0:Median1=Median2=Median3H9:Median1=Median2=Median3H0:Median=Median2=Median3H0:Median1>Median2>Median3 H0 : Not all populations of times are identical. Ha: All populations of times are identical. H0:Median1=Median2=Median3H3:Median1=Median2=Median3 H0: All populations of times are identical. Ha : Not all populations of times are identical. H0:Median1=Median2=Median3Ha:Median1=Median2=Median3H0:Median1=Median2=Median3Ha:Median1>Median2>Median3 H0 : Not all populations of times are identical. Ha: 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 conclusion. Do not reject H0. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Reject H0. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Do not reject H0. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Reject H0. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods
