Answer 1

there are N=50 data points.

so the first quartile will consist the data points from the first value to [N/4]th value

now [N/4]=[50/4]=[12.5]=12th value where [x] denotes the largest integer less than or equal to x

now 12th value = 21

since the data is in increasing order, Illinois' bachelor degree percentage rate of about 18%

so that falls in first quartile [answer]
