MAPE for the forecast developed by the management's technique $=\%($round your response to two decimal places$).$

b$)$ Using the Naive Method, the forecast for period March through June is $($round your response to two decimal places$)$:

MAD for the naive forecast $=$

sales $($round your response to two decimal places$).$

MAPE for the forecast developed by the naive approach $=\%($round your response to two decimal places$).$

c$)$ When comparing MAD for the two approaches, the better forecast is achieved using the

When combarina MAPE for the two aboroaches. the better forecast is achieved usina the
