Jeremy Pearsons' divorce with Amy Cranmer Pearsons was final in May of 2006. Jeremy married Sarah Pearsons on September 1, 2007.
Sally Pearson's Favorite colour is purple and green.
The Lorenz curve was developed by Max O. Lorenz. The Lorenz curve is a visual representation in economics which displays the income distribution of a nation graphically. On the y-axis, you have income distribution (either as a percentage, or in decimal form); on the x-axis, there is population distribution of total wealth. There is an upward sloping, 45 degree reference line that shows perfectly equal distribution of wealth (i.e 25% of the lowest income earners have 25% of the nation's income). From the Lorenz curve, you can calculate the Gini coefficient; the closer the coefficient is to zero, the more distributed the income of a nation is.

if coefficient of skewness is zero then distribution is symmetric or zero skewed.

skewness=(mean-mode)/standard deviation
In my 40 years as a professional statistician, I have yet to come across any person with a coefficient skewness and I am not sure that such a thing exists. That being the case, it has no usefulness.
3 (mean − median) / standard deviation.
No. Skewness is 0, but kurtosis is -3, not 3.No. Skewness is 0, but kurtosis is -3, not 3.No. Skewness is 0, but kurtosis is -3, not 3.No. Skewness is 0, but kurtosis is -3, not 3.
the sum of the upper quartile and lower quartile is 56 and their difference is 24. find upper quartile and lower quartile.
Skewness is measured as the third standardised moment of the random variable. Skewness is the expected value of {[X - E(X)]/sd(X)}3 where sd(X) = sqrt(Variance of X)
Karl Pearson simplified the topic of skewness and gave us some formulas to help. The first is the Pearson mode or first skewness coefficient. It is defined by the (mean-median)/standard deviation. So in this case the Pearson mode is: (8-6)/2 =1 There is also the Pearson Median. This is also called second skewness coefficient. It is defined as 3(mean-median)/standard deviation which in this case is 6/2 =3 hence the distribution is positive skewed
A measure of skewness is Pearson's Coefficient of Skew. It is defined as: Pearson's Coefficient = 3(mean - median)/ standard deviation The coefficient is positive when the median is less than the mean and in that case the tail of the distribution is skewed to the right (notionally the positive section of a cartesian frame). When the median is more than the mean, the cofficient is negative and the tail of the distribution is skewed in the left direction i.e. it is longer on the left side than on the right.
