A cost accountant is developing a regression model to predict the total cost of producing a batch of printed circuit boards as a function of batch size (the number of boards produced in one lot or batch). The dependent variable is . 3. A cost accountant is developing a regression model to predict the total cost of producing a batch of printed circuit boards as a linear function of batch size (the number of boards produced in one lot or batch).

A manager wishes to predict the annual cost (y) of an automobile based on the number of miles (x) driven. The following model was developed: y= 1,550 + 0.36x. If a car is driven 15,000 miles, the predicted cost is .6. A cost accountant is developing a regression model to predict the total cost of producing a batch of printed circuit boards as a linear function of batch size (the number of boards produced in one lot or batch), production plant (Kingsland, and Yorktown), and production shift (day, and evening). In this model, shift is .7. A multiple regression analysis produced the following tables.The regression equation for this analysis is . 8.
