χ2R:

Answer 1

Solution:

Question 1

Find the critical values χ2L and χ2R for the given confidence level c and sample size n.

We are given

c=0.9

n=26

So, critical values by using chi square table or excel are given as below:

χ2L = 14.6114

χ2R = 37.6525

Question 2

Find the critical values χ2L and χ2R for the given confidence level c and sample size n.

We are given

c=0.8

n=25

So, critical values by using chi square table or excel are given as below:

χ2L = 15.6587

χ2R = 33.1962
