Question: An organisation is trying to evaluate which of two PC computer systems to standardise on within the organisation. In terms of price, specification and performance there is little to choose between the two models being considered, Model A and Model B. However, the computer services manager is concerned about the possible maintenance and repair costs of the two models. Based on a sample of 40 of each type, the annual maintenance costs have been estimated at £45.60 for Model A, standard deviation £4.20, and at £39.65 for Model B, standard deviation £6.52. Would this information help the organisation choose between the two models?
