(b) Calculate the sample mean x¯.
(c) Calculate the sample standard deviation s.
(d) Determine the proportion of the data values that lies within x¯ ± 1.5s and compare with the lower bound given by Chebyshev's inequality.
(e) Determine the proportion of the data values that lies within x¯ ± 2s and compare with the lower bound given by Chebyshev's inequality.
