EXAMPLE 3.25

Select an SRS of countries using JMP. Refer to Example 3.23, where we selected an SRS of countries from a population of 189 countries. Also see Example 3.24, where we used the random digits in Table B to select the SRS. We can also use JMP to select an SRS. The output for the first 17 countries selected is displayed in Figure 3.8. JMP provides a file with the selected countries with all columns in the original data file. Note that the selected files are listed in the order that they appear in the original file, which is alphabetically in this case.
