1. Change number of sectors to 10 with >

2. Change color names to S (7) and F (3)

3. Click on Spin and record result (S or F)

4. Enter into chart on p. 260

5. Your chart should look like this (5 spins per sample):

Sample Number	Obs 1	2	3	4	5
1	F	F	S	S	S
2	S	S	S	S	F
	This is an example.

6. Do about ten trials (samples).

7. Fill out question #2 Relative Frequency Distribution

8. Skip the other questions but do #7 (by hand or on spreadsheet) and answer the question.

Case write up. Put this on a spreadsheet with all appropriate formulas and calculations. Do 30 samples and compare this to the result your group got. Do you see any difference? Do the chart for question #7 as well.
