Problem 2- (10 marks) An analyst must decide between two different forecasting techniques for weekly sales of inline skates: a linear trend equation and the naive approach. The linear trend equation is Ytu 124+ 2t, and it was developed using data from periods 1 through 10. Based on data for periods 11 through 19 as shown below, which of these two methods has greater accuracy?
