# Question: A random sample of data has a mean of 75

A random sample of data has a mean of 75 and a variance of 25.

a. Use Chebyshev's theorem to determine the percent of observations between 65 and 85.

b. If the data are mounded, use the empirical rule to find the approximate percent of observations between 65 and 85.
