The weekly growths (in cm) in saplings grown in a nursery are:1.0, 3.2

1.	The weekly growths (in cm) in saplings grown in a nursery are:1.0, 3.2, 1.4, 1.9, 2.4, 1.6, 1.4, 2.1, 1.3, 1.5 Find the mean growth.
Answer» Here, n = 10; x = weekly growth (in cm) of plant Mean of growth of plant: x̄ = \(\frac{Σx}{n}\) = \(\frac{1.0+3.2+1.4+1.9+2.4+1.6+1.4+2.1+1.3+1.5}{10}\) = \(\frac{17.8}{10}\) = 1.78 cm

The weekly growths (in cm) in saplings grown in a nursery are:1.0, 3.2, 1.4, 1.9, 2.4, 1.6, 1.4, 2.1, 1.3, 1.5 Find the mean growth.

Answer»

Here, n = 10; x = weekly growth (in cm) of plant

Mean of growth of plant:
x̄ = \(\frac{Σx}{n}\)
= \(\frac{1.0+3.2+1.4+1.9+2.4+1.6+1.4+2.1+1.3+1.5}{10}\)
= \(\frac{17.8}{10}\)
= 1.78 cm
