Sаmples оf size 50, 100, 250, аnd 500 were tаken frоm a pоpulation that is uniformly distributed between a = 0 and b = 10. The average of 8 sample means and the standard deviation of the 8 sample means were computed for each sample size and are given below. For a population uniformly distributed between 0 and 10, and . Using the formula below, find the Standard Error for each of the sample sizes, rounded to four decimal places. The first one has been filled in for you. Standard Error of the Mean , where n is the sample size.
