Simulation
From a very large (essentially infinite) population, of which half are men and half are women, you take a random sample, with replacement.
Use the following random number table and assume each single digit represents selection of one person; the odd numbers represent women and the even numbers (0, 2, 4, 6, 8) men.
a. Start on the left side of the top line (with 118) and count 10 people. What percentage of the sample will be men?
| 11848 |
80809 |
25818 |
38857 |
| 23811 |
80902 |
85757 |
33963 |
| 93076 |
39950 |
29658 |
7530 |
b. Start in the middle of the second line (with 857) and count 20 people. What percentage of the sample will be men?
c. If you were to repeat parts a and b many times, which sample would typically come closer to 50%-the sample of 10 or the sample of 20? Why?
