In a linear regression of weight lbs on height inches it was

In a linear regression of weight (lbs) on height (inches), it was found that b0 = -220 and b1 = 6. If a given individual is 72 inches tall, the regression predicts a weight of:

Solution

Here regression equation will be

weight=-220+6*height

For height= 72 inches predicted weight is

weight=-220+6*72=212 lbs

hence, the predicted weight is 212 lbs.
