Obviously, there are dumb middle class people and smart poor people. But on average/generally, do you think that poor people have slightly lower IQs than middle class people?
This could be tested by taking one million poor people and one million middle class people. Add up the IQs of each, then divide by one million. That will get you an average IQ for each class.
