Quizplus · Accepted Answer

We need to find the critical value of chi-squared ($\chi^2$) with 18 degrees of freedom ($n-1$, where $n$ is the sample size) and a 99% confidence level.

Using a chi-squared distribution table or calculator, we find that the critical value is approximately 37.156. Therefore, the correct answer is C.
