A sample of 100 sociology books has a mean cost of $76.75 and a standard deviation of $10.42. Using Chebyshev's rule, approximately what percentage of the 100 sociology books cost between $45.49 and $108.01?

A. 97%
B. 84%
C. 89%
D. 75%

Expert Solution

µ = 76.75

= 10.42

= 1 - 1/3²

= 0.89

= 89%

Option-C) 89%

A sample size of 120 had a sample mean and standard deviation of 100 and 15 respectively. Of these 120 data values, 3 were less than 70, 18 were between 70 and 85, 30 between 85 and 100, 35 between 100 and 115, 32 were between 115 and 130 and 2 were greater than 130. Test the hypothesis that the sample distribution was normal.
