The information here is the same for answering questions 35 to 36. Given the following sales data for the past 10 weeks, use a linear regression model to compute the forecast for week 11. Week 1 2 3 4 un 5 6 7 8 9 10 Sales 700 724 720 728 740 42 758 750 770 775 Sales Data by Week 800 780 760 740 Sales 720 700 680 660 640 620 600 1 2 3 4 5 6 7 8 Week 9 10
Let t = week number. What is the forecasting model to use? F(t) = 742.3 +18,2(t) F(t) = 699.4 + 15.1(t) F(t) = 742.3 + 14.8(t) F(t) = 699.4 +7.5(t) F(t) = 742.3 + 8.7(t)
What is the forecast for week 11? Choose the nearest answer if needed. 782 838 865 905 942
