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:

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 follows:


Parameter Estimates



Identify and interpret the estimate for the SPEED β-coefficient,  1.
◦ 1 = 3.57; For every $1 increase in PRICE, we estimate SPPED to increase by about 4 megahertz, holding CHIP fixed.
◦ 1 = 3.57; For every 1-megahertz increase in SPEED, we estimate PRICE to increase $3,57, holding CHIP fixed.
◦ 1 = 105; For every $1 increase in PRICE, we estimate SPEED to increase 105 megahertz, holding CHIP fixed.
◦ 1 = 105; For every 1-megahertz increase in SPEED, we estimate PRICE (y) to increase $105, holding CHIP fixed.
