# of CoursesFrequencyRelative FrequencyCumulative Relative Frequency
1300.60.6
215 0.3 0.9
35 0.1 1

 

1.) Proportion of students taking exactly 2 courses: 0.3 or 30%

2.) Proportion of students taking 1 or 2 courses:

Total Frequency Of student taking 1 courses+ Total frequency of student taking 2 courses = 30 + 15 = 45

Cumulative relative frequency of students taking one or two courses = 45/50 = 0.9

This means that Proportion of students taking 1 or 2 courses is 0.9 or 90%
