Tall girls Refer to Exercise 10. (a) Make a graph of the population distribution. (b) Sketch a possible dotplot of the distribution of sample data for the SRS of size 20 taken by the AP Statistics class.

The Coefficient of Variation: C.V. = S / x(bar) X(bar) Mean of data Examples: #1 X(bar) 54 ft S 26 ft C.V. = S / x(bar) = 26/54 = .48 or 48% #2 X(bar) 2 hours S 2.7 hours C.V. = 2.7 / 2 = 1.35 NOTICE: the units cancel when you divide the two numbers, therefore the answer does not have units!! Chebyster’s Theorem: For any set of numbers with mean x(bar) and standard...
