4.1 The subjoined gives the sum of pints of symbol B order used at Woodlawn Hospital in the departed 6 weeks:

a) Forestall the insist for the week of October 12 using a 3-week affecting middle.b) Use a 3-week momented affecting middle, after a while moments of .1, .3, and .6, using .6 for the most new-fangled week. Forestall insist for the week of October 12.c) Compute the forestall for the week of October 12 using exponential smoothing after a while a forestall for August 31 of 360 and a 5 .2. PX

4.3 Refer to Problem 4.2. Develop a forestall 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 forestall on a graph after a while the objective basis and the easy forestall. Fixed on a visual inadvertence, which forestall is improve?

(a) None manifest.

(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. affecting middle.

4.5 The Carbondale Hospital is because the acquisition of a new ambulance. The firmness accomplish security in-part on the anticipated mileage to be driven instant year. The miles driven during the departed 5 years are as follows:

a) Forestall the mileage for instant year (6th year) using a 2-year affecting middle.b) Find the MAD fixed on the 2-year affecting middle. (Hint: You accomplish possess simply 3 years of matched basis.)c) Use a momented 2-year affecting middle after a while moments of .4 and .6 to forestall instant year’s mileage. (The moment of .6 is for the most new-fangled year.) What MAD results from using this path to forestalling? (Hint: You accomplish possess simply 3 years of matched basis.)d) Compute the forestall for year 6 using exponential smoothing, an primal forestall for year 1 of 3,000 miles, and a 5 .5. PX

4.25 The subjoined gives the sum of accidents that take-placered on Florida State Highway 101 during the departed 4 months:

Forecast the sum of accidents that accomplish take-place in May, using least-squares return to resolve a bend equation.PX

4.27 George Kyparisis owns a assembly that manufactures sailboats. Objective insist for George’s sailboats during each of the departed four seasons was as follows:

George has forestalled that annual insist for his sailboats in year 5 accomplish correspondent 5,600 sailboats. Fixed on this basis and the multiplicative seasonal standard, what accomplish the insist roll be for George’s sailboats in the burst of year 5?
