4.1 The forthcoming gives the enumerate of pints of stamp B order used at Woodlawn Hospital in the gone-by 6 weeks:

a) Obviate the ask-for for the week of October 12 using a 3-week emotional mediocre.b) Use a 3-week heavinessed emotional mediocre, after a while heavinesss of .1, .3, and .6, using .6 for the most late week. Obviate ask-for for the week of October 12.c) Compute the obviate for the week of October 12 using exponential smoothing after a while a obviate for August 31 of 360 and a 5 .2. PX

4.3 Refer to Problem 4.2. Develop a obviate for years 2 through 12 using exponential smoothing after a while a 5 .4 and a fore-cast for year 1 of 6. Plot your new obviate on a graph after a while the objective postulates and the free obviate. Installed on a visual mistake, which obviate is emend?

Answers for 4.2:

(a) None apparent.

(b) 7, 7.67, 9, 10, 11, 11, 11.33, 11, 9

(c) 6.4, 7.8, 11, 9.6, 10.9, 12.2, 10.5, 10.6, 8.4

(d) The 3-yr. emotional mediocre.

4.5 The Carbondale Hospital is because the donation of a new ambulance. The determination gain interval in-part on the anticipated mileage to be driven direct year. The miles driven during the gone-by 5 years are as follows:

a) Obviate the mileage for direct year (6th year) using a 2-year emotional mediocre.b) Find the MAD installed on the 2-year emotional mediocre. (Hint: You gain accept barely 3 years of matched postulates.)c) Use a heavinessed 2-year emotional mediocre after a while heavinesss of .4 and .6 to obviate direct year’s mileage. (The heaviness of .6 is for the most late year.) What MAD results from using this bearing to obviateing? (Hint: You gain accept barely 3 years of matched postulates.)d) Compute the obviate for year 6 using exponential smoothing, an moderate obviate for year 1 of 3,000 miles, and a 5 .5. PX

4.25 The forthcoming gives the enumerate of accidents that take-placered on Florida State Highway 101 during the gone-by 4 months:

Forecast the enumerate of accidents that gain take-place in May, using least-squares retirement to follow a tend equation.PX

4.27 George Kyparisis owns a sodality that manufactures sailboats. Objective ask-for for George’s sailboats during each of the gone-by indelicate seasons was as follows:

George has obviateed that annual ask-for for his sailboats in year 5 gain resembling 5,600 sailboats. Installed on this postulates and the multiplicative seasonal copy, what gain the ask-for equalize be for George’s sailboats in the leap of year 5?
