Find the critical value X2R corresponding to a sample size of 6 and a confidence level of 95 percent. Round to three decimal places.
Solution:
n = 6
At 95% confidence level the is ,
= 1 - 95% = 1 - 0.95 = 0.05
/ 2 = 0.05 / 2 = 0.025
/2,df = 0.025,5 = 12.833
and
1- /2,df = 0.975,5 = 0.831
2L = 2/2,df = 12.833
2R = 21 - /2,df = 0.831
