Answer 1

20.

Data MA(3) Forecasts Abs. Error Error2 Abs. % Error 5.4 8 3.7 = 13 5.7 13 – 5.7 = 7.3 (13 5.7)2 = 53.29 13-5.7 13 56.15% 15 - (15 15 8.2333 = 8.2333 6.7667 8.2333)2 = 45.7878 15-8.2333 15 45.11% = 12 10.5667 12 - 10.5667 = 1.4333 (12 - 10.5667)2 = 2.0544 12-10.5667 12 11.94% 13.3333

The absolute percentage error is 56.15.

(Answer 21):

Expected profit = No of units X Profit making units percentage x Profit - No of units X Loss making units percentage x Loss

= 111 x 0.968 x 79 - 111 x 0.032 x 3.6

= 8488.392 - 12.792

= 8475.60.

Answer 27:Probability of Cumulative sales less than 160 is (6+7)/(6+7+4+3+3) = 13/23 = 0.56
