For a particular company, the cost of a flat screen TV is dependent on its size. Six TVs are randomly selected and the size (x) and the cost (y) are recorded below.

X (size in inches): 40, 34, 58, 24, 62, 60

Y (cost): $650.50 $459.80 $703.90 $310.15 $855.90 $789.45

a) Find the simple linear regression equation that best fits this data using techniques of linear regression.

b) If a TV were 44 inches, using the equation you chose aboce, what would you predict the cost to be?
