You plan a study of factors associated with fertility

(a woman’s number of children) in a Latin American city.

Of particular interest is whether migrants fromother cities or migrants from rural areas differ from natives of the city in their family sizes. The groups to be compared are urban natives, urban migrants, and rural migrants. Since fertility is negatively related to educational level, and since education might differ among the three groups, you control that variable. Table 13.22 shows some of the data for a random sample of married women above age 45. Analyze the complete data, which are the Fertility data file at the text website. In your report, provide graphical presentations as well as interpretations for all your analyses, and summarize the main results.
