If you wish to estimate a population mean with a sampling distribution error SEequals0.22 using a​ 95% confidence interval and you know from prior sampling that sigma squared is approximately equal to 5.8​, how many observations would have to be included in your​ sample? The number of observations that would have to be included in your sample is nothing.
