Forecasting can be broadly considered as a method or a technique for estimating many future aspects of a business or other operation. There are numerous techniques that can be used to accomplish the goal of forecasting. For example, a retailing firm that has been in business for 25 years can forecast its volume of sales in the coming year based on its experience over the 25-year period—such a forecasting technique bases the future forecast on the past data.

valid. Except in the case of step variable costs, it’s ordinarily assumed that relationship between cost and volume is a strictly linear. Economist correctly point out that many costs that the accountant classifies as variable actually behave in a curvilinear fashion, that is the relation between cost and activity is a curve. Although many costs are not strictly linear, a curvilinear cost can be satisfactorily approximated with a straight line within a narrow band of activity (relevant range).

Based on the hypothesis test, that was conducted to compare the difference between the two different insurances, it is concluded that patients with managed care insurance are paying more charges than the patients with commercial insurance.
