Question

he eggs of a species of bird have an average diameter of 23 mm and an SD of 0.45 mm. The weights of the chicks that hatch from these eggs have an average of 6 grams and an SD of 0.5 grams. The correlation between the two variables is 0.75 and the scatter diagram is roughly football shaped.
The intercept of the regression line for estimating chick weight based on egg diameter is _______________ grams.

The diameter of one of the eggs is 0.5 mm wider than that of another. According to the regression method, the chick that hatches from the bigger egg is estimated to be ____________ grams hea
