Question

-----33-----

The table below was obtained by using data for 40 males. The response (y) variable is weight (in pounds), and the predictor (x) variables are HT (height in inches), WAIST (waist circumference in cm), and CHOL (cholesterol in mg).

(Round to the nearest whole number as needed.)

Explanation / Answer

Best regression is y =?199+2.2*HT+2.1*WAIST?0.1*CHOL because its R square 0.873   is larger other R square values.

If a male has a height of?72?in, a waist circumference of?102?cm, and a cholesterol level of?263mg,

The best predicted value of this male's weight is

= ?199+2.2*72+2.1*102?0.1*263 = 147.3 pound
