Unformatted text preview: economist to study the relationship between a woman’s education (EDU_YRS) and the number of children that she has (NUM_KID). A random sample of 2,589 Canadian women is drawn. Using the sample of 2,589 Canadian women the following OLS line and coefficient of correlation are estimated: NUM_KID-hat = 5.1 – 0.2*EDU_YRS r = -0.3132 (a) What kind of data are these? (b) How should you interpret these results? What is the meaning of 5.1? What is the meaning of -0.2? What is the meaning of -0.3132? (c) Is the scatter diagram a good description of these data? Explain. Aside from using statistics such as the coefficient of correlation and least squares line, what is another way to summarize the relationship between these two variables? 5 10 NUM_KID, NUM_KID_hat 5 10 15 20 25 30 EDU_YRS n = 2,589 NUM_KID_HAT = 5.1 - 0.2*EDU_YRS...
