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.
