Question

Consider the following frequency table for the number of children in American families. What percentage of American families have no children? Number of Children Number of families (millions) 0 35.54 1 14.32 2 13.28 5.13 3 4 or more 1.97 13.2% 10.1% ОО 7.00% 50.6%

Answer 1

To find the percertage of families have no children you need to find the total numer of families:

`35.54+14.32+13.28+5.13+1.97=70.24`

As the total of families is 70.24 millions you consider this data as the 100% of the families.

Then, you calculate the percentage of families have no children as follow:

Families have no children: 35.54million

Total number of families: 70.24 million

`35.54\cdot(100)/(70.24)=50.59`Then, the percentage of families have no children is approximately 50.6%
