Question

Suppose that a population has a mean of 200 and a standard deviation of 26. a. Compute the standard error of the sample mean for a sample size of 10.

Answer 1

Given:

Mean = 200

Standard deviation = 26

a) Find the standard error for a sample size of 10:

`E=(\sigma)/(√(N))`

Substitute the values:

`E=(26)/(√(10))=8.22`

Answer: 8.22
