Question
**Finding Critical Chi-Square Values for Confidence Intervals** To determine the critical values \(\chi^2_L\) and \(\chi^2_R\) for a given confidence level \(c\) and sample size \(n\), follow these steps: Given: - Confidence Level (\(c\)): 0.98 - Sample Size (\(n\)): 20 **Instructions:** 1. Compute \(\chi^2_L\) by using a chi-square distribution table or calculator. Round the result to three decimal places as needed. Note: In using chi-square tables, the degrees of freedom is \(n - 1\). Understanding these concepts will help you construct accurate confidence intervals for variance and standard deviation in statistical analyses.
