Dr. Cribari would like to determine if there is a
statistically significant difference between her two Math 2830
classes. To make this comparison she will compare the results
from exam 1. Class one had 35 students take the exam with a
mean of 82.6 and a population standard deviation of 1.41.
Class two had 32 students take the exam with a mean of 84 and
a population standard deviation of 3.63. Can Dr. Cribari
conclude that there is difference in the mean test grades
between the two classes at a=0.05?
