Question

if x bar equals to 25 and coefficient of variation is 20 find variation​

Answer 1

Answer:

Answer:

Variance = 25

Step-by-step explanation:

x bar = 25

co - efficient of Variation = 20%

Also,

C.V = (S.D. ÷ x bar) × 100

then

20 = S.D ÷ 25) × 100

20 × 25 = 100S.D

÷ 100

5.00 = S.D

S.D. = 5

W.K.T.,

Variance =(S.D)²

Variance = 5²

Variance = 25
