If the standard deviation is 9 and sample size is 100 then the standard error is 0.9.
Given that the mean is 80,standard deviation be 9 and sample size be 100.
We are required to find the standard error of the given data.
The standard error of a statistic is basically the standard deviation of its sampling distribution or an estimate of that standard deviation.
Standard error=σ/
in which σ is standard deviation and n is sample size.
Here standard deviation is 9 and sample size is 100.
Standard deviation=9/
=9/10
=0.9
Hence if the standard deviation is 9 and sample size is 100 then the standard error is 0.9.
