Suppose that scores on this test have a mean of 100 and a standard deviation of 22 . Complete the following statements about the distribution of scores on this personality test.

(a) According to Chebyshev's theorem, at least 8/9 (about 89%) of the scores lie between X and X. (Round your answer to the nearest integer.)

b) According to Chebyshev's theorem, at least? % of the scores lie between 56 and 144 .

(c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately % (c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately

d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the scores lie between X and X?
