The method of least squares was used to develop a cost equation to predict the cost of receiving purchased parts at a video game manufacturer Ninety: six data points from monthly data were used for the regression. The following computer output was received: Intercept 155,800 Slope 395 The cost driver used was number of parts inspected. Required: 1. What is the cost formula? Total cost of receiving - s 2. Using the cost formula from Requirement 1, Identity each of the following: Independent variable, dependent variable, Variable rate per professional hour, and fixed cost per month. Independent variable Dependent variable per part inspected Variable rate per professional hour Fixed cost per month 3. Using the cost formula, predict the cost of recelving for a month in which 8,600 parts are inspected Total cost of receiving - S
