Of the 500 students:
Honor: 205
Got Math Class: 125
Didnt: 80
Not: 295
Got Math Class: 215
Didnt: 80
Lets say our 100% are 205 and 295, for honor and nor honor roll students.
Honor:
125 is x percent of 205
125/205 = 0.6098
0.6098 * 100 = 60.98
In the honor roll students, 60.98% got the math class they requested.
100 - 60.98 = 39.02
39.02% did not get the math class they requested.
Not Honor:
215 is x percent of 295
215/295 = 0.7288
0.7288 * 100 = 72.88
In the not honor roll students, 72.88% got the math class they requested.
100 - 72.88 = 27.12
27.12% did not get the math class they requested.
Using the data we collected, we can assume honor roll students do not have a better chance at getting the class they requested. In fact, we found out that the students not in honor roll had a higher chance of getting their requested class.
