Question

Determine the critical values for the confidence interval for the population variance from the given values. Round your answers to three decimal places.

n=14 and α=0.01.

Answer 1

We have given,              
              
Sample size =n=14      
Degree of freedom =n-1=   13  
Level of significance=0.01      
              
by using chi square critical value table or Excel =CHIINV(1-(0.01/2),13)
by using chi square critical value table or Excel =CHIINV((0.01/2),13)
