Quizplus · Accepted Answer

The critical value $\chi _ { L } ^ { 2 }$ for a sample size of 9 (degrees of freedom = 8) and a 90% confidence level can be found using a chi-square distribution table. For the lower critical value, we look at the 5th percentile (0.05) for 8 degrees of freedom, which is approximately 2.733.
