Question 7.102

1. Use the Simple Random Sample applet to choose the sample of songs in Example 4 (on page 299). Here’s how:

Assign labels 01 to 27 by entering 27 in the “Population 1 to” box and clicking “Reset.”
Then enter 4 in the “Select a sample of size” box and click “Sample.”

Which songs from the list in Example 4 (page 299) make up your sample? Click “Reset” and choose another sample. Which songs did you choose this time? You see that random sampling gives different samples each time—what matters is that all songs have the same chance to be chosen.
