We are asked to find the left and right critical values.
The confidence level is 95%
Significance level = 1 - 0.95 = 0.05
Sample size: n = 9
Degree of freedom = n - 1 = 9 - 1 = 8
So, the significance level is 0.05 and the degree of freedom is 8.
Using any chi-square critical value table or calculator,
Left critical value: χ²L = 2.733
Right critical value: χ²R = 15.507
Therefore, the chi-square left and right critical values are
2.733, 15.507
