Question

Quizplus · Accepted Answer

The critical value $\chi^2$ for a given confidence level and sample size can be found using a $\chi^2$ distribution table or calculator, with degrees of freedom $df = n - 1$ (where $n$ is the sample size). For a sample size of 19, $df = 19 - 1 = 18$. At a 99% confidence level, the critical value for 18 degrees of freedom is approximately $37.156$.
