When the sample standard deviation is based on a random sample of size n from a normal
Question:
(a) Use this result to obtain an unbiased estimator for = of the form cnS, when the constant cn depends on the sample size n.
(b) Find the value of cn for n = 10 and n = 25. Generally, how well does S perform as an estimator of for large n with respect to bias?
