a . α = 0.01 b . α = 0.005 c . α = 0.10

a.

Expert Solution
Check Mark
To determine

Determine the critical value of χ2 , if α=0.01 .

Answer to Problem 1PS

The critical value is 6.635.

Explanation of Solution

The critical value of χ2 from χ2 -table which is given in table E.4 at degree of freedom 1 and upper tail value 0.01, if α=0.01 is 6.635.

Therefore, the required critical value is 6.635.

b.
