We believe that 80 of the population of all Calculus I students consider calculus an exciting subject. Suppose we randomly and independently selected 24 students from the population.
If the true percentage is really 80, find the probability of observing 23 or more of the students who consider calculus to be an exciting subject in our sample of 24. A) 0.033057 B) 0.004722 C) 0.028334 D) 0.966943
Question 2
A history instructor has given the same pretest and the same final examination each semester. He is interested in determining if there is a relationship between the scores of the two tests.

B) There is a strong positive correlation between the tests.
C) There is a strong negative correlation between the tests.
D) The correlation is something other than linear.
