Answer 1

Answer:

For a frequency distribution Median = 40 , 1st Quartile Q1 = 30 and coefficient of skewness j = 0.2 Find the third Quartile Q3

Answer 2

coefficient of skewness = (q3 + q1 - 2q2)/(q3-q1)

0.2 = (x+ 30 - 2×40) / (x-30)

0.2 = (x-30-20)/(x-30) = 1- 20/(x-30)

25=x-30

x = 55

Q3 = 55
