Question 1

Suppose that the student taking 22 credit hours in the data set in the previous question was actually taking 28 credit hours instead of 22 (so we would replace the 22 in the data set with 28). Indicate whether changing the number of credit hours for that student would make each of the following summary statistics increase, decrease, or stay about the same:
a. mean
b. median
c. range
d. IQR
e. standard deviation

Question 2

All students in a physical education class completed a basketball free-throw shooting event and the highest number of shots made was 32. The next day a student who had just transferred into the school completed the event, making 35 shots.  Indicate whether adding the new student's score to the rest of the data made each of these summary statistics increase, decrease, or stay about the same.
a. mean
b. median
c. range
d. IQR
