Height (cm) | Number of persons |
120 | 3 |
130 | 4 |
140 | 5 |
150 | 6 |
160 | 2 |
Given:
Height (cm) | Number of Persons |
120 | 3 |
130 | 4 |
140 | 5 |
150 | 6 |
160 | 2 |
Formula Used:
Solution:
Total height = 120×3 + 130×4 + 140×5 + 150×6 + 160×2 = 2800 cm
Total number of persons = 3 + 4 + 5 + 6 + 2 = 20
Mean height == 140.00 cm
The mean height of the persons is 140.00 cm.
