Apply Chebyshev’s Inequality and so called empirical rule on the following Serum-cholesterol data (measured in mg/100ml): 120.82, 86.2, 124.2, 92.6, 95.19, 103.4, 95.3, 80.6, 84.3, 103.3. Discuss the application of these rules to the given data.
How is Chebyshev’s Inequality useful for describing a set of observations? When can the empirical rule be used instead?
