Extracted text: When the sample standard deviation S is based on a random sample from a normal population distribution, it can be shown that E(S) = V2/(n - 1)r(n/2)a/T((n - 1)/2) Use this to obtain an unbiased estimator for o of the form cS. What is c when n = 16? (Round your answer to four decimal places.)
