**miraclegers**, Friday, March 21, 2014 at 6:09am0.833 grams per mm is correct:

slope=rsd(y)/sd(x)=0.75*0.5/0.45

slope is 0.8333 grams per mm

The intercept of the regression line for estimating chick weight based on egg diameter is

Intercept=mean y - slope *mean x

Intercept = 23 - 0.8333* 6 = 18
