Using a set of five dice, roll the dice and determine the mean number of dots showing on the five dice. Repeat the experiment until you have 25 sample means.

a. Draw a dotplot showing the distribution of the 25 sample means. (See Example 7.2, p. 364.)

b. Describe the distribution of x’s in part a.

c. Repeat the experiment to obtain 25 more sample means and add these 25 x’s to your dotplot.

Describe the distribution of 50 means.
