Consider the following data set.

21 34 5 16 33 21 22 8 14 35 21 27 34 33

a. Draw a graph similar to Fig. 3.5 on page 133.

b. Compare the percentage of the observations that actually lie within two standard deviations to either side of the mean with that given by Chebyshev’s rule with k = 2.

c. Repeat part

(b) with k =3.
