Hi all, I have a stats questions that's been bugging me all day at work. I would appreciate it if someone could enlighten me! I have a population consisting of 9000 people who are classified into 3 groups: A = 2000 B = 4000 C = 3000 I randomly create a sample consisting of 3000 observations: A = 800 B = 1400 c = 800 What's the best way to test the likelihood of obtaining such an extreme sample and whether this sample is indeed random enough. Cheers
