Explanation Given Information: The average life span of the car compounding services is 3 years and standard deviation is 0.2 years and age of the company is 2.6 years. Formula Used: The mean of the set of values x 1 , x 2 , ... , x n is the average of all values which means sum of all values divided by the number of values. According to the Chebyshev’s rule, for a set of data at least 3 / 4 of the values will lie within two standard deviations of the mean or in the interval [ x ¯ − 2 s , x ¯ + 2 s ] . Calculation: Consider the average life span and standard deviation of the internet based company, μ = 3 and σ = 0.2 . The distribution associated to the company is highly skewed, therefore, Chebyshev’s rule is used. Evaluate the values for one standard deviations, of the mean. x ¯ − s = 3 − 0.2 = 2.8 And, x ¯ + s = 3 + 0.2 = 3.2 Evaluate the values for two standard deviations of the mean
