Variance of the sampling distribution

#### Explanation:

Given-

Sample size

Standard Deviation of the population distribution

From the above information, we can get the standard deviation of the sampling distribution or standard error.

#SE=sigma/sqrtn=10/sqrt11#

Variance of the sampling distribution
