Is an unbiased estimator of the variance σ2. In other words, E(s2) = σ2. Is s = √s2 an unbiased estimator of the standard deviation σ? If not, does s tend to underestimate or overestimate the standard deviation? Hint: Very little computation is needed. Start by writing the formula for computing the variance of s.
