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
