The method of least squares was used to develop a cost equation to predict the cost of receiving. Ninety-six data points from monthly data were used for the regression. The following computer output was received:
Intercept ......... 23,100
Slope .......... 316
The driver used was number of parts inspected.
1. What is the cost formula?
2. Using the cost formula from Requirement 1, identify each of the following: independent variable, dependent variable, variable rate, and fixed cost per month.
3. Using the cost formula, predict the cost of receiving for a month in which 2,500 parts are inspected.
