A data set has a mean of 135, a median of 137, and a standard deviation of 13. Marrion concludes that 99.7% of the data in the set must have values between 96 and 174. What flaw, if any, is there in Marrion’s reasoning? Pick only one. A. Marrion should have calculated three standard deviations from the median instead of calculating three standard deviations from the mean. B. There is no flaw in Marrion’s reasoning. He calculated three standard deviations...

*Data Set Listed Below* Use the sample mean and standard deviation to find the values related to the Empirical Rule.          The Empirical Rule: For a set of data whose distribution is approximately normal, about 68% of the data are within one standard deviation of the mean. about 95% of the data are within two standard deviations of the mean. about 99.7% of the data are within three standard deviations of the mean. Use the value of n and the...
