Answer 2

The mean height of plant is  62.17 cm.

Explanation:

The complete quiestion:

The height of 72 plants in a garden are given below. Make two columns in height and no of plants

Height (in cm)        :58  60   62   64   66   68

Number of plants : 12   14    20   13    08   05

Find the mean height.

We know that,

Mean = $\dfrac{f_{1}x_{1}+f_{2}x_{2}+f_{3}x_{3}+.......}{f_{1}+f_{2}+f_{3}+..... }$

= $\dfrac{58\times 12+60\times 14+62\times 20+64\times 13+66\times 8+68\times 5}{12+14+20+13+8+5}$

= $\dfrac{4476}{72}$

= 62.17 cm

∴ The mean height of plant =  62.17 cm

Thus, the mean height of plant is  62.17 cm.
