Required

1. For each of the months January through June, inclusive, prepare a rolling forecast of sales volume.

2. For each of the months March through June, determine the three-month forecast error rate, defined as 1 minus the absolute percentage error. For example, the forecast error rate for March's sales is found by dividing the absolute value of the forecast error for this month by the actual sales volume for the month. The forecast error for any month (e.g., March) is defined as the difference between the actual sales volume for the month and the sales volume for that month forecasted three months earlier (e.g., December).
