Answer #1

Solution :

What is a Quartile?

A Quartile divides a rank-ordered set into four equal parts.The values are called first(Q1), second(Q2) and third (Q3) quartile.

In that Q1 =P₂₅

Q2 = P₅₀

Q3 = P₇₅

The formula of locator is given by :

L = (k/100) * n

Here n = 36 - Total number of observations

k = 75

Therefore

L = 0.75 * 36 =27

Thus P₇₅ is the 27th value in sorted data i.e 64.

P₇₅ = 64
