# Prob Set-up: Sampling Methods and the Central Limit Theorem

The area of study is Sampling Methods and the Central Limit Theorem

Consider all of the coins (pennies, nickels, quarters, etc.) in your pocket or purse as a population.Make a frequency table beginning with the current year and counting backward torecord the ages (in years) of the coins. For example, if the current year is 2004, then a coinwith 2002 stamped on it is 2 years old.

Now I have the following table showing coins with year stamped on it

Type of coins year stamped year-old

Two-dollar 1: 1996 9

Two-dollar 2: 1996 9

One-dollar 1: 1989 16

One-dollar 2: 1989 16

One-dollar 3: 1987 18

One-dollar 4: 1993 ...
