In each case, consider what you know about the distribution and then explain why you would expect it to be or not to be normally distributed.
a. The lifetimes of a set of batteries manufactured by a company in your town.
b. The list of guesses of the number of marbles in a large jar is filled with marbles at a neighborhood picnic.
c. The scores at an archery contest.
d. The heights of all the 1st grade students at your school
This is asking what YOU would expect, not what we would expect.
