Answer:
standard error of the mean (S.E) = 0.06
Step-by-step explanation:
Explanation:-
Given sample size 'n' = 500
Given variance of the Population = 900
The standard deviation of the Population = √900 = 30
The standard error of the mean is determined by
[tex]S.E = \frac{S.D}{\sqrt{n} } = \frac{30}{500} = 0.06[/tex]
