Question: Consider the following data set. a. Draw a graph similar to Fig. 3.5. Fig. 3.5 b. Compare the percentage of the observations that actually lie

Consider the following data set.

a. Draw a graph similar to Fig. 3.5.

Fig. 3.5

X-3s 27.8 x-2s X-S X 35.2 42.6 50.0 X+S x + 2s

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.

X-3s 27.8 x-2s X-S X 35.2 42.6 50.0 X+S x + 2s 57.4 64.8 x + 3s 72.2
