Do not round intermediate calculations. Total Yearly Quarter 1 Quarter 2 Quarter 3 Quarter 4 Sales Year 1 4 16 8 5 33 2 9 18 8 52 3 16 26 13 76 4 19 27 20 92 5 21 32 19 100 6 23 37 20 112 7 27 42 27 130 17 21 26 28 32 34
a. Compute the centered moving average values (first find Four-Quarter Moving Average) for this time series (to 3 decimals). Centered Moving t Sales Average 4 16 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 8 5 9 18 17 8 16 26 21 13 19 27 26 20 21 32 28 19 23 37 32 20 27 42 34 27
