Question 1172262: There 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 110 and a standard deviation of 21 . Complete the following statements about the distribution of scores on this personality test.
According to Chebyshev's theorem, at least
36%,56%,75%,84%,89%
of the scores lie between 68 and 152 .
