Chebyshev's theorem and the empirical ruleThere are dozens of personality tests available on the World Wide Web. One test, scored on a scale of 0 to 200, is designed to give an indication of how "personable" the test taker is, with higher scores indicating more "personability."
Suppose that scores on this test have a mean of 108 and a standard deviation of 24. Complete the following statements about the distribution of scores on this personality test.
(a) According to Chebyshev's theorem, at least (56%, 75%, 84%, 89%) of the scores lie between 60 and 156.
(b) According to Chebyshev's theorem, at least (56%, 75%, 84%, 89%) of the scores lie between 72 and 144.
(c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately (69%, 75%, 95%, 99.7%) of the scores lie between 60 and 156.
(d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 99.7% of the scores lie between (_____) and (______).
Thanks. I'll get the answers back to you in just a few minutes.

Thank you for your patience. Here are the solutions:

(a) The values 60 and 156 are within 2 standard deviations of the mean. According to Chebyshev's Theorem, the percentage of values between these two limits is 1 - (1/2)^2 = 1 - 1/4 = 3/4 = 75%.

(b) The values 72 and 144 are within 1.5 standard deviations of the mean. According to Chebyshev's Theorem, the percentage of values between these two limits is 1 - (1/1.5)^2 = 1 - (2/3)^2 = 1 - 4/9 = 5/9 ≈ 56%.

(c) The values 60 and 156 are each 2 standard deviations from the mean. According to the Empirical Rule, 95% of the values will be between these limits.

(d) According to the Empirical Rule, 99.7% of the scores will be within 3 standard deviations of the mean. For this distribution those limits are 108 - 3(24) = 36 and 108 + 3(24) = 180.

Please feel free to ask if you have questions about any of these solutions.

Thanks,

Ryan
