Question

a survey asked how many children people have. the survey results are given in the histogram above. find the relative frequency of people who have 4 children.

Explanation:

Step1: Find total frequency

Sum the frequencies for each number of children: \(3 + 2 + 5 + 4 = 14\)

Step2: Find relative frequency for 4 children

Relative frequency = Frequency of 4 children / Total frequency = \(\frac{4}{14}=\frac{2}{7}\approx0.2857\)

Answer:

\(\frac{2}{7}\) (or approximately \(0.286\))
