A dendritic tree is a branched structure that emanates

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 seven 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 was selected, and the resulting counts were as follows:30

 

 

The mean of these counts is 35.67 and the standard deviation is 9.99. Suppose we want to construct a 95% confidence interval for the population mean.We could calculate the standard error as

 

 

(a) On what grounds might the above analysis be criticized? (Hint: Are the observations independent?)

(b) Using the classes [15, 20), [20, 25), and so on, construct a histogram of the data. Does the shape of the

distribution support the criticism you made in part (a)? If so, explain how.
