You've been asked to use the following historical sales information to forecast next year's sales for Worldwide Widget Manufacturing, Inc. The actual sales for 2016 were $1,950,000. Year: 2011 sales 1,750000 2012 sales 2,000,000 2013 sales 1,350,000 2014 sales 2,250,000 2105 sales 1,800,000. What would be next year's forcast using the naive approach and the average sales approach? What would be the MAPE using the naive approach and the average sales approach? Can someone show me how to do this and show me how you got the answers?
