Stamp Printing Corp., a book printer, has provided the following data: Stamp Printing Corp., a book printer, has provided the following data:    Management believes that the press setup cost is a mixed cost that depends on the number of titles printed. (A specific book that is to be printed is called a  title . Typically, thousands of copies will be printed of each title. Specific steps must be taken to setup the presses for printing each title-for example, changing the printing plates. The costs of these steps are the press setup costs.) Required: Estimate the variable cost per title printed and the fixed cost per month using the least-squares regression method.
