Answer 1

Answer:

The height of the tallest girl is 151 as well as the height of shortest girl is 128

Range=23

Mean=141.4

5 Girls have more height than the mean

Step-by-step explanation:

Range=Maximum height -Minimum height

So, Maximum height is 151 and minimum height is 128

Therefore, Range =151-128

=23

Mean=135+150+139+128+151+132+146+149+143+141/Total number

=1414/10

=141.4

5 girls have more height than the mean

Answer 2

1. the tallest girl's height is 151
2. the height of shortest girl is 128
3. range of data= tallest - shortest

=> 151 - 128 = 23

4. mean height

$\frac{135 + 150 + 139 + 128 + 151 + 132 + 146 + 149 + 143 + 141}{10} \\ = > \frac{1414}{10} = 141.4$

5. no of girls having height more than mean height is 5
