Normal distribution populations with a subset of the population that is not norm. Dis

Identify an example of a population that you would expect to be normally distributed. Explain why, according to you, it would be normally distributed. Then, describe a subset of the population you identified and explain why it would not be normally distributed and what the distribution would look like.

I need some help with this because I had an idea that I could use human heights as the normal population distribution and heights of basketball players for the subset that is not normally distributed. I just need help with how to put it. Thanks
