Illustration 11.28. In a continuous frequency distribution grouped in intervals of 2, the first four moments about the Mean (=10) ex- pressed in class-interval units are, 0, 2.8, -2 and 24.5 respectively. Obtain the first four moments about Mean and calculate B1 and 82. Also calculate the coefficient of skewness based on moments and comment on kurtosis.
