I. Use Chebyshev’s theorem to find what percent of the values will fall between 156 and 276 for a data set with a mean of 216 and standard deviation of 12.
II. Use the Empirical Rule to find what two values 68% of the data will fall between for a data set with a mean of 219 and standard deviation of 20.

Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
See your later post. 
Obviously, this is not a repost as I only posted this question once. So if someone else posted the same question, I have NO control over what they do.
