Retail price data for n = 60 hard disk drives were recently reported in a computer magazine. Three variables were recorded for each hard disk drive as shown to the right.. y = Retail PRICE (measured in dollars) X₁=Microprocessor SPEED (measured in megahertz) (Values in sample range from 10 to 40) X₂ - CHIP size (measured in computer processing units) = (Values in sample range from 286 to 486) A first-order regression model was fit to the data. Part of the printout is shown below. Interpret the interval given in the printout. OBS SPEED CHIP Dep VarPRICE 5099.0 1 33 286 Predict Std Err Lower 95% Value Predict 4464.9 260.768 .... Predict 3942.7 Upper 95% Predict 4987.1 Residual 634.1 O A. We are 95% confident that the average price of all hard drives falls between $3,943 and $4,987. O B.
