Answer 2

Answer:

The variance is 9.

Step-by-step explanation:

Variance is the average of the squared differences from the mean of a set of data. Variance is the difference between the mean and the consequent data point. Often, this sign is used to represent variation: σ². Analysts and traders both use it to assess market security and volatility.

Given,

Mean (AM) = 6

coefficient of variation (C.V.) = 50%

Let the standard deviation(SD) be 'σ'.

Now, C.V. = σ/Mean

⇒ 50/100 = σ/6

⇒ 6/2 = σ

⇒ σ = 3

∴ Variance (x) = σ²

⇒ x = 3²

⇒ x = 9

Hence, the variance is 9.
