A 6th grade teacher was interested in comparing two ways of
teaching math to her students. She used method A with one of her
existing classes and method B with another one. She flipped a coin
to decide which class would receive method A. At the end of the
year her students obtained the following scores (percent correct)
on a comprehensive math exam. Method A: 75, 82, 88, 93, 69, 72, 78,

Since we are attempting to examine the behavior of a class of
students, the behavior of an individual (as we calculated in
objective 1) is really of little concern to us. Assuming that there
are 30 students enrolled for a typical class, use the central limit
theorem to calculate the following:
• What would be the shape of the
distribution of the average class grade of these 30 students?
• What would be the average class
