Answer:

b. 5, 5, 8, 10, 11, 18

Step-by-step explanation:

The first frequency remains constant as the first value of cumulative frequency.

The second value of cumulative frequency is the summation of 1st cumulative frequency and the previous frequency value and so on.

Cumulative frequencies:

5,

5 + 0 = 5,

5 + 3= 8,

8 + 2 = 10,

10 + 1 = 11,

11 + 7 = 18 therefore;

Cumulative frequencies:

5, 5, 8, 10, 11, 18.
