Question

If a population of scores has a mean of 45 and a standard deviation of 13.23, what is the standard error of the corresponding distribution of means when the sample size is equal to 101 and the sample mean is equal to 47? Please provide at least two decimal places when providing your answer.

Answer 1

Solution :

Given that ,

mean = = 45

standard deviation = = 13.23

n = 101

sampling distribution of standard deviation

standard error   =  / n =13.23 / 101 =1.32

= 1.32
