Find the critical values for a 90% confidence interval using the chi-square distribution with 6 degrees of freedom. Round the answers to three decimal places.
The Critical values are _____ and ______.
Solutions
Expert Solution
We have given,
Sample size =n= 7
Degree of freedom =n-1=6
Level of significance=1-0.90=0.1
by using chi square critical value table or Excel
=CHIINV(1-(0.1/2),6)
by using chi square critical value table or Excel
=CHIINV((0.1/2),6)
| The Critical values are 1.635 and 12.592 |
