Question

The table below summarizes the number of children per household for a sample of 36 high-income families.

Answer 1

Using the given table, it is found that the mean number of children per household for these families is of 2.33.

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

Researching the problem on the internet, the table states that:

• 2 households have 4 children.

• 16 households have 2 children.

• 13 households have 3 children.

• 5 households have 1 children.

The total number of children is given by:

T = 2 x 4 + 16 x 2 + 13 x 3 + 5 x 1 = 84

Hence the mean number of children for the 36 households is given by:

M = 84/36 = 2.33.
