b) Use the Empirical Rule to find what two values 95% of the data will fall between for a data set with mean 234 and standard deviation of 12
An aptitude test has a mean of 220 and standard deviation of 10. find the corresponding z score for: a) a test score of 232 b) a test score of 212
(1) (a) z1 = (Mean - x1)/SD = (135 - 120)/7.5 = 2 and z2 = (Mean - x2)/SD = (135 - 150)/7.5 = -2
According to Chebyshev's ...
The solution shows how the Chebyshev Theorem can be used to compute the percentage values that fall in a given interval.
