27. Finding Critical Values In constructing confidence intervals for or we use Table A-4 to find the critical values and but that table applies only to cases in which so the number of degrees of freedom is 100 or smaller. For larger numbers of degrees of freedom, we can approximate and by using where k is the number of degrees of freedom and is the critical z score first described in Section 7-2. STATDISK was used to find critical values for 189 degrees of freedom with a confidence level of 95%, and those critical values are given in Exercise
