A collector of grandfather clocks believes that the price received for the clocks at an auction increases with the number of bidders, but at an increasing (rather than a constant) rate. Thus, the model proposed to best explain auction price (y, in dollars) by number of bidders (x) is the quadratic model

E(y) = β₀ + β₁x + β₂x²

This model was fit to data collected for a sample of 32 clocks sold at auction; a portion of the printout follows:
_____________________________________________________________________

ROOT MSE 133 R-SQUARE 893

DEP MEAN 1327 ADJ R-SQ .885

An outlier for the model is a clock with a residual that _____ in absolute value. (Fill in the blank.)
◦ exceeds 399
◦ is less than 266
◦ exceeds .893
◦ exceeds 133
