What statistic test to use? I am new to statistics!
I have 2 groups of city population based on education level (group A: educated, group B: without education)
I try to figure out if there is a difference between the number of people who live in the city, based on education
What statistic tests to use to prove the following hypothesis, or what steps to follow?
I already calculated mean and standard deviation for both groups, and I also know N for both, but I am stuck from here, what test to use.
H0: no difference between education level
Ha: more "educated" people than "without education" in the city
Ha2: more "without education" people than "educated" people in the city
Also, is it possible to have 2 alternative hypothesis, or I should think to state the Ha as a single hypothesis? How can I make it into 1 alternative hypothesis?
Thanks!


Usually, the t-test comes into play for this (check its assumptions). Also, have a look at a general procedure.
