WebMargin of error is often associated with sample size calculation to estimate the tolerance of interest of statistic included in the experiments. The need for samples in statistics Sampling plays an important role in probability & statistics for the following reasons. The finite subset of population is required because 1. Websample SD is just sample SD SE of the mean is equal to (sample SD)/sqrt(n) The thing is that here, we don't have a sample standard deviation. But we do have a pilot study that tells us that the population SD is 15km, and so hopefully, we can trust that. And if we use population SD, we use z*, not t*.
