Arnold Sorenson, production manager of New Frontiers Instruments Inc., was interested in estimating the mathematical relationship between the number of electronic assemblies produced during an 8-hour shift and the average cost per assembly. This function would then be used to estimate cost for various production order bids and to determine the production level that would minimize average cost. Arnold collected data from nine shifts during which the number of assemblies ranged from 100 to 900. In addition, he obtained the...
