Question

If random samples of size 11 are drawn from a population with mean 7 and standard deviation 3 , find the standard error of the distribution of sample means. Round your answer to three decimal places, if necessary. standard error

Answer 1

Here,

n = 11

mean = 7

Standard Deviation (σ) = 3

S.E. = ?

We know that,

S.E. = σ/$\sqrt{n}$

S.E. = 3/$\sqrt{11}$

∴ S.E. = 0.905 Ans.
