To find the percentage of the values between two values.
a) Utilize Chebyshev's theorem to find what percent of the values will fall between 120 and 150 for a data set with mean of 135 and standard deviation of 7.5.
b) Utilize the Empirical Rule to find what two values 95% of the data will fall between for a data set with mean 234 and standard deviation of 12.
