Find the critical​ values, chi Subscript 1 minus alpha divided by 2 Superscript 2 and chi Subscript alpha divided by 2 Superscript 2​, for​ 95% confidence and nequals12. Round to the nearest thousandth.

Solutions

Expert Solution

Solution:

At 95% confidence level the is ,

= 1 - 95% = 1 - 0.95 = 0.05

/ 2 = 0.05 / 2 = 0.025

/2,df = 0.025,11 = 21.920

and

1- /2,df = 0.975,11 = 3.816

2L = 2/2,df = 21.920

2R = 21 - /2,df = 3.816
