A study of commuting times reports the travel times to work of a random sample of 1010 employed adults in Chicago. The mean is x = 53.0 minutes and the standard deviation is s = 53.9 minutes. What is the standard error of the mean? (Round your answer to four decimal places.)

Respuesta :

Answer:

standard error of the mean = 1.6960

Step-by-step explanation:

Given -

Mean [tex](\overline{X})[/tex] = 53 minutes

Standard deviation ( s ) = 53.9 minutes

n = 1010

standard error of the mean  =  

[tex]\sigma _{\overline{X}}[/tex]    =   [tex]\frac{s}{\sqrt{n}}[/tex]

        = [tex]\frac{53.9}{\sqrt{1010}}[/tex]

       =  1.6960
