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
e. standard deviation

Question 2

d. IQR stay about the same

Answer to Question 2

The way students get to school does seem to be independent of gender. Overall, 34 of students ride the bus, compared to 35 of the boys and 33 of the girls. 44 of all students caught rides with someone and 22 used personal transportation, almost the same as the percentages for boys (43 and 22) or girls (44 and 23) separately. These data provide little indication of a difference in mode of transportation between boys and girls at this school.
