Answer:
The percent of students who take exactly three courses =
31.67%
Explanation:
a) Data and Computations:
# of Courses Frequency Relative Frequency Cumulative Frequency
1 22 0.3667 22
2 19 0.3167 41
3 19 0.3167 60
Number of part-time students surveyed = 60
Students who take 1 course = 22/60 * 100 = 36.67%
The cumulative frequency for 1 course is 22 students.
The frequency of student who take 2 courses = 19(41 - 22)
Therefore, the frequency of students taking 3 courses = 19 (60 - 41) and
the relative frequency of students who take 3 course = 19/60 * 100 = 31.67%.
