Quizplus · Accepted Answer

For a chi-square distribution with n-1 degrees of freedom (9 in this case) and a significance level of 0.01, the critical values are found using chi-square distribution tables or calculators. The critical values for a two-tailed test at α = 0.01 are approximately 1.735 and 23.589.
