EXPLANATION

Now, we need to complete the table as shown as follows:

As the total number of students is 115, n=115

AGE Cumulative Cumulative Cumulative Percentage

Frequency Relative Frequency

10-19 24 24/115 = 0.208 20.8%

20-29 25 25/115 = 0.217 20.8+21.7 = 42.5%

30-39 15 15/115 = 0.13 42.5%+13.04= 55.5%

40-49 26 26/115 = 0.22 55.5 + 22.6 = 78.1%

50-59 19 19/115 = 0.165 78.1 + 16.5 = 94.5%

60-69 2 2/115 = 0.017 94.5 + 1.73 = 96.2%

70-79 4 4/115 = 0.034 96.24 + 3.47 = 100%
