Note the similarities in the following parallel treatments of a frequency distribution and a probability distribution.

Frequency Distribution

Complete the table below for the following data. (Recall that x is the midpoint for the interval.)

14,7,1,11,2,3,11,6,10,13,11,11,16,12,9,11,9,10,7,12,9,6,4,5,9,16,12,12, 11,10,14,9,13,10,15,11,11,1,12,12,6,7,8,2,9,12,10,15,9,3

a. Find the mean (or expected value) for each distribution.

b. Find the standard deviation for each distribution.

c. (Extra credit) Use the normal approximation of the binomial probability distribution to find the interval that contains 95.44% of that distribution.
