Question:
Which one of the following statements is correct?
Which one of the following statements is correct?
Options:
- a) Coefficient of variation of X is strictly more than coefficient of variation of Y.
- b) Coefficient of variation of X is strictly less than coefficient of variation of Y .
- c) Coefficient of variation of X is the same as coefficient of variation of Y .
- d) Coeficient of variation cannot be determined from the given data. Direction for Questions (97-98): Consider the following for the two (02) items that follow: Let X be a random variable following binomial distribution with parameters n = 6 and p = k. Further, 9P(X = 4) = P(X = 2).

correct answer : b)
Explanation:
C.V(X) = σ
M ×100
=
2
50 100×
= 22
C.V(Y) = σ
M ×100
=
3
50 100×
= 23
\ C.V(X) < C.V(Y)
C.V(X) = σ
M ×100

= 22
C.V(Y) = σ
