A Random Sample of Size 15 Taken from a Normally

Short Answer

A random sample of size 15 taken from a normally distributed population resulted in a sample variance of 25. The upper limit of a 99% confidence interval for the population variance would be: $\begin{array}{|l|l|}\hline \text { A. } & 12.868 . \\\hline \text { B. } & 92.032 . \\\hline \text { C. } & 85.896 . \\\hline \text { D. } & 75.100. \\\hline\end{array}$
