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 Slope 167,100 445 The cost driver used was number of parts inspected. Required: 1. What is the cost formula? Total cost of receiving = $ +($ x ) 2. Using the cost formula from Requirement 1, identify each of the following: independent variable, dependent variable, Variable rate per professional hour, and fixed cost per month. Independent variable Dependent variable Variable rate per professional hour Fixed cost per month per part inspected 3. Using the cost formula, predict the cost of receiving for a month in which 6,800 parts are inspected. Total cost of receiving = S
