A simple random sample of 100 items from a population with $σ=8$ has a standard error of mean : |
0.08 12.5 0.8 6.25 |
0.8 |
Given population standard deviation $\sigma=8$ and sample size $n=100$. Standard error of mean: $SE=\frac{\sigma}{\sqrt{n}}$ $SE=\frac{8}{\sqrt{100}}$ $SE=\frac{8}{10}=0.8$ final answer: $0.8$ |
