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.

How many girls have heights more than the mean height?

Dear Student

First we have to arrange the given data in an ascending order,
= 128, 132, 135, 139, 141, 143, 146, 149, 150, 151
5 girls have heights more than the mean height (i.e. 141.4 cm).

​Thanks
