Find the Critical Values and Determine the Appropriate Distribution
Do one of the following as appropriate:
a) Find the critical value t (alpha/2)
b) Find the critical value z (alpha/2)
c) State that neither the normal nor the t distribution applies.
Problem: 95%; n= 40; sigma is unknown; population appears to be skewed.

If u look up 5% on the two tail with 39 degrees of freedom=40-1,
you get: 2.02.
This mean Probability(-2.02<=t<=2.02)=0.95
b) Find the critical value z(alpha/2)
5% critical value ...
