Question 336416
I would like to calculate the test statistics for the following hypothesis: can someone help me?? 
Do countries that are members of G-20 have a lower unemployment rate than countries that are not members? 
Null: Mean of member’s unemployment rate is lower
Alternative: Mean of member’s unemployment is higher
Alpha: 0.05 
---------------------
Note: The null hypothesis MUST contain equality.
Ho: u(G20 members)-u(not members) = 0
Ha: u(G20 members)-u(not members) > 0
