Five identical containers (shoe boxes, paper cups, etc.)
must be prepared for this problem, with contents as follows:
There are five boxes containing red and white items
(such as marbles, poker chips, or colored slips of paper).
Box
Contents
#1
15 red and 15 white
#2
30 red and 0 white
#3
23 red and 5 white
#4 20
red and 10 white
#5
10 red and 20 white
Select one of the boxes at random
so that you don't know its contents.
Step 1 Shake
the box.
Step 2 Select
one marker, note the result, and return it to the box.
Step 3 Repeat
the first two steps 20 times with the same box.
a. What do you think is inside the box you
have sampled?
b. Could you have guessed the contents by
repeating the experiment five times? Ten times?
Do you think you should have more than 20 observations
per experiment?
