Two different forecasting techniques (F1 and F2) were used to forecast demand for cases of bottled water. Actual demand and the two sets of forecasts are as follows: PREDICTED DEMAND

Period Demand F1 F2
1 68 63 62
2 75 66 61
3 70 73 70
4 74 65 71
5 69 71 73
6 72 69 73
7 80 70 76
8 78 72 80

a.
Compute MAD for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 2 decimal place.)

MAD F1
MAD F2

(Click to select)F1F2None appears to be more accurate.

b.
Compute the MSE for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 2 decimal places.)

MSE F1
MSE F2

(Click to select)F1F2None appears to be more accurate.

c.
In practice, either MAD or MSE would be employed to compute forecast errors. What factors might lead a manager to choose one rather than the other?

Either one might already be in use, familiar to users, and have past values for comparison. If (Click to select)control chartstracking signals are used, MSE would be natural; if (Click to select)tracking signalscontrol charts are used, MAD would be more natural.

d.
Compute MAPE for each data set. Which forecast appears to be more accurate? (Round your intermediate calculations to 2 decimal places and and final answers to 2 decimal places.)

MAPE F1
MAPE F2

Case in point 2.4 attaway airlines, part two back at attaway airlines, the morning meeting ended with no agreement between dan esposito and molly kinnon. in fact, a new issue arose. molly now says that the new accounting system is entitled to the highest priority because the federal government soon will require the reporting of certain types of company-paid health insurance premiums. because the current system will not handle this report, she insists that the entire accounting system is a nondiscretionary project. as you might expect, dan is upset. can part of a project be nondiscretionary? what issues need to be discussed? the committee meets again tomorrow, and the members will look to you, as the it director, for guidance.

Daniel owns 100 shares of abc corporation's common stock. abc uses the fair value option, and recent declines in the firm's credit rating have caused the value of the firm's outstanding bonds payable to drop by 10%. daniel feels this is good news, but he wants to know what you think about the situation. which of the following represents your best response? a : "this situation may be positive for you in that the change in abc's credit standing indicates that the value of the firm's assets is likely increasing. however, the drop in bond value may negate any positive effects on your bottom line, because it means your claim on the firm's assets is simultaneously decreasing." b : "actually, this is bad news all around. the drop in the value of abc's bonds payable means shareholders' claims on the firm's assets have decreased. moreover, abc's declining credit rating means that the firm's assets are probably also dropping in value, thus magnifying your losses even more." c : "on the surface, this seems like good news because it means your claim on the firm's assets has increased. however, the drop in creditworthiness may also indicate that abc's assets are declining in value, thus offsetting any gains associated with the drop in bonds payable." d : "you're right! this is good news because it means that abc's debtholders have a decreased claim on the firm's assets. as a result, the firm's existing shareholders"like you"have seen their claim on the firm's assets increase."
