Question: Suppose when designing the experiment in question 4, that the effect of the input/output buffer size was studied in addition to the effect of data file size. Thus, instead of the one-factor completely randomized design, the experiment used a two-factor factorial design, with the first factor, buffer size, having two levels (20 kilobytes and 40 kilobytes) and the second factor, data file size, having three levels (small, medium, and large). A sample of four programs was evaluated for each buffer size and data file size combination. The access times are recorded on the tab Access2. Analyze the data. Compare your results with those obtained in question 2. (10 points)
