Question

1. Relative frequency is the number of observations associated with a single value or range of values compared with the total number of observations within all ranges of values. Complete Table 1 and indicate the proportion of women who have had less than 3 children and the proportion of women who have had two or three children in a selected group of 20 women. Present the information in Table 1 in the form of an appropriate chart [4]

Table 1. Frequency distribution of the number of children of 20 women

Number of children	Frequency	Relative frequency	Cumulative frequency	Cumulative relative frequency
0	4
1	8
2	4
3	2
4+	2
	20

Answer 1

Formula Reference:

The proportion of women who have had less than 3 children

Frequency for less than 3 children = 4+8+4 = 16

Total number of children = 20

The proportion of women who have had less than 3 children is then 16/20 = 0.80

The proportion of women who have had two or three children in a selected group of 20 women:

2 0r 3 children = 4+2 = 6

so the propotion is 6/20 = 0.30
