Question

Find the χ2 critical values

a. χ² _{(20, .025)}

b. χ² _{(2, .05)}

c. χ² _{(18, 10)}

d. χ² _{(16, .95)}

e. χ² _{(30, .90)}

f. χ² _{(80, .995)}

Answer 1

Solution:-

a) χ2 (20, .025)

n = 20

df = n-1 = 20 -1 = 19

= 0.025  

χ2 = 32.85

b) n = 2

df = n-1 = 2 -1 = 1

= 0.05  

χ2 = 3.84

c)  n = 18

df = n-1 =18 -1 = 17

= 0.10

χ2 =24.77

d) n = 16

df = n-1 =16 -1 = 15

= 0.95

χ2 = 7.26

e)  n = 30

df = n-1 =30 -1 = 29

= 0.90

χ2 = 19.77

f)  n = 80

df = n-1 =80 -1 = 79

= 0.995

χ2 = 50.38
