b) If the sample size is 150, by Chebyshev's rule, at least how many measurements are in the interval within two SDV of the mean? Show your reason or work. c) If the sample size is 150 and we assume the data set is mound shaped, by empirical rule, approximately how many measurements is beyond the interval two SDV of the mean? Show your reason or work. That means, they are either belowor above
