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...
