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.

I am really having a hard time understanding this. Any help would be great.

a. The wealth of the parents of students attending your
school

b. The values that a group of fourth-grade students
would give for the length of a segment that they
measured with a ruler

c. The SAT or ACT examination scores in mathematics
for students who were in your high school
graduation class

d. The weights of all incoming freshman students at
your school
