A sample is obtained from a population with s = 20.If the sample mean has a standard error of 5 points,then the sample size is n = 4.

Question

The formula for the standard error is SE = s/√n, where s is the sample standard deviation and n is the sample size. Given that s = 20 and SE = 5, we can solve for n:

5 = 20/√n

√n = 20/5

√n = 4

n = (4)^2

n = 16

Therefore, the sample size is not 4, but rather 16. So, the statement is false.
