Sara Fowler, who is in charge of information technology at Cergo Corporation, must decide whether to purchase additional memory for her department’s three computers or to buy additional new computers to increase her department’s productivity. Six weeks ago, Fowler installed additional memory on Computer CM. She is impressed with the processing improvement, but she has yet to decide between the two courses of action. Information on the number of bytes processed per nanosecond by each computer for the past ten weeks is as follows.

Fowler has asked you to analyze the two courses of action based on the assumption that two memory upgrades can be purchased for the price of one new computer. Your analysis is to include the computation of the average weekly output per nanosecond for Computers CN and CP, a comparison of that average with the output of Computer CM, and the computation of the weekly difference between the average output and the output of Computer CM. What course of action do you recommend?
