Answer 1

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%.
