Answer:
SE=$128.13
Step-by-step explanation:
-Given the sample mean is $34,250 and standard deviation is $2,050 with n=256:
-Standard error is calculated using the formula:
[tex]SE=\frac{s}{\sqrt{n}}[/tex]
Where s is the sample standard deviation.
#We substitute our values to solve for SE:
[tex]SE=\frac{s}{\sqrt{n}}\\\\=\frac{2050}{\sqrt{256}}\\\\=128.125\approx128.13[/tex]
Hence, the standard error is $128.13
