Let kids denote the number of children ever born to a woman, and let educ denote years of education for the woman. A simple model relating fertility to years of education is

Kids = β(0) + β(1) educ + E

Step-by-step explanation:

Kids = β(0) + β(1) educ + E

Where "E" stands in for other factors, such as maybe an error in the estimated age of the mother, an error in the predicted income level, or even an error in religion. And we all know for certainty, that whereever education is being discussed, age and income would always be related.

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
