2071 Old Q. No.5 Person's coefficient of skewness for a distribution is 0.4 and its coefficient of variation is 30%. If mode is 88, find mean and median.​

Step-by-step explanation:

Given

--- coefficient of variation

Required

The mean and the median

The coefficient of variation is calculated using:

Where:

mean

So:

Express percentage as decimal

Make the subject

The coefficient of skewness is calculated using:

This gives:

Make the subject

Equate both expressions for

Cross multiply

Collect like terms

Divide both sides by -0.88

Hence:

Calculate

So:

Also, the coefficient of skewness is calculated using:

Multiply both sides by 30
