Suppose it is desired to estimate the variance of the tensile strength of a particular type of thread. For 21 pieces of this type of thread, E (X; – Xave)² = 2000. Suppose also it is desired to build a two-sided 95% confidence level estimate for the true variance tensile strength. What tabled Chi-Square value should be used in arriving at its upper confidence limit?
