Following are the weights (in kg) of 10 new born babies in a hospital

1.	Following are the weights (in kg) of 10 new born babies in a hospital on a particular day:3.4, 3.6, 4.2, 4.5, 3.9, 4.1, 3.8, 4.5, 4.4, 3.6Find the mean \(\overline{X}\)
Answer» The weight (in kg) of 10 new born babies = 3.4, 3.6, 4.2, 4.5, 3.9, 4.1, 3.8, 4.5, 4.4, 3.6 Therefore, Mean \(=\frac{Sum\, of \, weight}{Total\,babies}\) \(=\frac{3.4 + 3.6 + 4.2 + 4.5 + 3.9 + 4.1 + 3.8 + 4.5 + 4.4 + 3.6}{10}\) \(=\frac{40}{10}\) = 4 kg

Following are the weights (in kg) of 10 new born babies in a hospital on a particular day:3.4, 3.6, 4.2, 4.5, 3.9, 4.1, 3.8, 4.5, 4.4, 3.6Find the mean \(\overline{X}\)

Answer»

The weight (in kg) of 10 new born babies = 3.4, 3.6, 4.2, 4.5, 3.9, 4.1, 3.8, 4.5, 4.4, 3.6

Therefore, Mean \(=\frac{Sum\, of \, weight}{Total\,babies}\)

\(=\frac{3.4 + 3.6 + 4.2 + 4.5 + 3.9 + 4.1 + 3.8 + 4.5 + 4.4 + 3.6}{10}\)

\(=\frac{40}{10}\)

= 4 kg
