1.	The numbers of children in 10 families of a locality are:2, 4, 3, 4, 2, 0, 3, 5, 1, 1, 5Find the mean number of children per family.
Answer» The number of children in 10 families: 2, 4, 3, 4, 2, 0, 3, 5, 1, 1, 5 Therefore, Mean \(=\frac{Total\, children}{Total\,families}\) \(=\frac{2 + 4 + 3 + 4 + 2 + 0 + 3 + 5 + 1 + 1 + 5}{10}\) \(=\frac{30}{10}\) = 3

The numbers of children in 10 families of a locality are:2, 4, 3, 4, 2, 0, 3, 5, 1, 1, 5Find the mean number of children per family.

Answer»

The number of children in 10 families:

2, 4, 3, 4, 2, 0, 3, 5, 1, 1, 5

Therefore, Mean \(=\frac{Total\, children}{Total\,families}\)

\(=\frac{2 + 4 + 3 + 4 + 2 + 0 + 3 + 5 + 1 + 1 + 5}{10}\)

\(=\frac{30}{10}\)

= 3
