You are asked to identify how well a researcher's sample statistic represents their population parameter. The researcher provides you with the following information about the sample and population of interest: =1000
n
=
1000

=10,000
N
=
10
,
000

=250
μ
=
250

¯=240
x
¯
=
240

=50
σ
=
50

Using the information above, help the researcher identify how well their sample statistic represents their population parameter by calculating the standard error
