2. The maager of a small health cliic would like to use expoetial smoothig to forecast demad for laboratory services i their facility. However, she is ot sure whether to use a high or low value of α. To make her decisio, she would like to compare the forecast accuracy of a high ad low α o historical data. She has decided to use α = 0.7 for the high value ad α = 0.1 for the low value. Give the followig historical data, which do you thik would be better to use? Week Demad (labour requiremet) 1 330 2 350 3 320 4 370 5 368 6 343 3. A compay uses expoetial smoothig with tred to forecast mothly sales of its products, which show a tred patter. At the ed of week 5, the compay wats to forecast sales for week 6. The tred through week 4 has bee 20 additioal cases sold per week. Average sales have bee 85 cases per week. The demad for week 5 was 90 cases. The compay uses α =.20 ad β =.10. Make a forecast icludig tred for week 6.

After reviewig the iformatio above, Joh tells Mary ad Peter that o arbitrage opportuities ca arise from these prices. Mary disagrees with Joh. She argues that oe could use the followig portfolio to obtai arbitrage profit: Log oe call optio with strike price 40; short three call optios with strike price 50; led $1; ad log some calls with strike price 55. Peter also disagrees with Joh. He claims that the followig portfolio, which is differet from Mary s, ca produce arbitrage profit: Log 2 calls ad short 2 puts with strike price 55; log 1 call ad short 1 put with strike price 40; led $2; ad short some calls ad log the same umber of puts with strike price 50. Which of the followig statemets is true? (i) Oly Joh is correct. (ii) Oly Mary is correct. (iii)oly Peter is correct. (iv) Both Mary ad Peter are correct. (v) Noe of them is correct.
