This document contains statistical information about the heights of professional basketball players in a frequency table. It then provides questions to analyze the data, including finding the mean, standard deviation, class limits, class midpoints, class boundaries, sample size, and class width. It also provides a word problem about selecting a fundraising committee and calculating probabilities of selecting women, men or college graduates.

4.
A fund raising committee is to be selected from a group of 30 members, including
20 college graduates (15 of whom are women) and 10 people who did not
graduate from college (4 of whom are women).
a. If the chairperson is randomly selected, find the probability of getting a
woman.
a)
19C1/30C1 = 19/30 = 0.634

3. b. If a chairperson is randomly selected, find the probability of getting a man
or a college graduate.
11/30 + 20/30 - 5/30 = 26/30 =0.867
c. If two different members are randomly selected, find the probability that
they are both women.
19C2/30C2 = 0.3931
