Answer to Question 1

a. mean increase
b. median stay about the same
c. range increase
d. IQR stay about the same
e. standard deviation increase

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.
