The heights of 10 girls were measured in cm and the results are as follows: 135, 150, 139, 128, 151, 132, 146, 149, 143, 141.

What is the mean height of the girls?

Dear Student

First we have to arrange the given data in an ascending order,
= 128, 132, 135, 139, 141, 143, 146, 149, 150, 151
Mean height of the girls = Sum of height of all the girls/ Number of girls
= (128 + 132 + 135 + 139 + 141 + 143 + 146 + 149 + 150 + 151)/ 10
= 1414/10
= 141.4 cm

Thanks
