Could you please help me in exercise 3

Exercise 3:
1. Recall the Chebyshev' rule.
2. Given the following data sets. The sample mean and sample standard deviation are as follows:
a. Which data set has a larger variation? (justify your answer)
b. Is Chebyshev' rule verified for these two data sets. (Justify your answer graphically).
c. What can we conclude?
3. In 1903, K. Pearson and A. Lee published the paper “On the Laws of Inheritance in Man. I. Inheritance of Physical Characters” (Biometrika, Vol. 2, pp. 357–462). The article examined data on forearm length, in inches, for a sample of 140 men. The mean and standard deviation of the forearm lengths are 18.8 in. and 1.12 in., respectively.
a. Apply Chebyshev’s rule with k = 2 to make pertinent statements about the forearm lengths
of the men in the sample.
b. Repeat part (a) with k = 3.
