Question:

Why should you feel uncomfortable making a prediction in Exercise 10.3 for a rate of 70?

Exercise 10.3

If, as a result of ongoing changes in the role of women in society, we saw a change in the age of childbearing such that the high-risk fertility rate jumped to 70 in Exercise 10.1, what would we predict for the incidence of birthweight

Exercise 10.1

The following data are from 10 health-planning districts in Vermont. Y is the percentage of live births ≤ 2500 grams. X1 is the fertility rate for women ≤ 17 or ≥ 35 years of age (X1 is known as the “high-risk fertility rate.”). X2 is the percentage of births to unmarried women.

Compute the regression equation for predicting the percentage of births of infants weighing less than 2500 grams (Y) on the basis of the high-risk fertility rate (X1).

Use R, or SPSS, or any other available program to accomplish this (and the next several questions).

I am assuming that you will use R, or SPSS, or any other available program to answer many of the questions in this chapter, However, it is not very difficult to obtain the results by hand calculation.image text in transcribed
