Question
A dendritic tree is a branched structure that emanates from the body of a nerve cell. In a study of brain development, researchers examined brain tissue from 36 adult guinea pigs. The investigators randomly selected nerve cells from a certain region of the brain and counted the number of dendritic branch segments emanating from each selected cell. A total of 36 cells (1 per pig) was selected, and the resulting counts were as follows:

Explanation / Answer
I think that the population mean within 2 cells has no meaning, more information is needed to clarify actually what the question is. Please check the question again.
