Using Multiple Regression Results to Construct and Apply a Cost Formula The controller for Dohini Manufacturing Company felt that the number of purchase orders alone did not explain the monthly purchasing cost. He knew that nonstandard orders (for example, one requiring an overseas supplier) took more time and effort. He collected data on the number of nonstandard orders for the past 12 months and added that information to the data on purchasing cost and total number of purchase orders March Number of Number of Purchasing Purchase Nonstandard Month Cost Orders Orders January $18,860 370 S3 February 18,065 330 19,250 370 April 18,050 410 May 19,345 400 June 19,500 450 55 July 19,670 460 30 August 20,940 560 80 September 19,430 440 October 20,020 500 November 18.800 470 12 December 19,340 480 27 Multiple regression was run on the above data; the coefficients shown by the regression program are: 14,460 (rounded to the nearest Intercept dollar) X variable 1 8.8 (rounded to the nearest cent) variable 2 20.32 (rounded to the nearest cent) Required: 1.
