Problem 10E

To find the variance of a hypergeometric random variable in Example 2.3-4 we used the fact that Prove this result by making the change of variables k = x − 2 and noting that References Example 2.3-4 Step-by-Step Solution:

Answer:

Step 1 of 3:

To find the variance of a hypergeometric random variable.

Let X be the hypergeometric distribution.

Here, n selected from N = n = x + (n - x) ,   where ‘x’ selected from and (n - x) selected from .

Therefore, Then ,

E(X) = =  =   =   Therefore, Step 2 of 2
