Chapter 5, Problem 10E(choose chapter or problem)
A sample of size 101 from a normal population has sample standard deviation s = 40. The lower and upper 0.025 points of the \(\chi_{100}^{2}\) distribution are \(\chi_{100,0.975}^2=74.222\) and \(\chi_{100,0.025}^{2}=129.561\). Use these values to construct a 95% confidence interval for \(\sigma\).
