39) Computer MSE for the above forecasts A. 96.03 B. 96.33 C. 90.16 D. 95.03 Use the following information for questions 40 Year 460 450 455 565 580 500 2 525 550 40) Using the method indicated in your book to compute seasonally adjusted forecast for q3 (quarter 3) of year 3 A. 630.12 B. 629.26 C. 625.03 D. 620.11 41) The given trend equation is Y= 1840 + 135 * year. The seasonal factor for August is 0.15 Forecast sales for August of year 10 A. 478.5 B. 450.5 C. 490.5 D. 495.3 42) Which of the following is not a qualitative forecasting method? A. Delphi method B. Management judgment C. Jury of executive opinion D. Exponential smoothing

Explanation / Answer

For question number 39 no supporting data is available

Question no.4

So i have calculated seasonal factor

so seasonal factor is here.

Now we will see the trend for year 2.

y (2 year) = 1975 + 2 * (21110 -1975) = 2245

Now the seasonally adjusted forecast for q3 for year 3 = 2245 * 1.1212/4 = 629.26

Option C is correct.

Question 41

Here trend question

Y = 1840 + 135 * Year

so for Year = 10 years

Y (10) = 1840 + 135 * 10 = 3190 units

so now season factor for August = 0.15

so sales in August = 3190 * 0.15 = 478.5

(42) Exponential smoothing is a quantitative forecasting methods. Option D is correct.

Year (X) 1 2 Sum Seasonal Factor q1 450 455 905 0.8862 q2 500 525 1025 1.0037 q3 565 580 1145 1.1212 q4 460 550 1010 0.9890 1975 2110 4085 4
