Consider the following data:

Month	Jan-12	Feb-12	Mar-12	Apr-12	May-12	Jun-12	Jul-12	Aug-12	Sep-12
Profit ($)	5,450	5,203	4,884	4,517	5,110	5,438	6,019	6,117	5,859

Step 1 of 5: Determine the three-period moving average for the next time period. If necessary, round your answer to one decimal place.

Step 2 of 5: What are the MAD, MSE and MAPE scores for the three-period moving average? Round any intermediate calculations, if necessary, to no less than six decimal places, and round your final answer to one decimal place.

Step 3 of 5: Determine the three-period weighted moving average for the next time period with weights of 3 (most recent), 2 (second recent), and 1 (oldest time period).If necessary, round your answer to one decimal place.

Step 4 of 5: What are the MAD, MSE and MAPE scores for the three-period weighted moving average forecast? Round any intermediate calculations, if necessary, to no less than six decimal places, and round your final answer to one decimal place.

Step 5 of 5:

Based on theMAD scores, which forecast is best?
