Answer:
Height of the tallest girl: 151 cm
Height of the shortest girl: 128 cm
Range of the Data: 22 cm
Mean height of the girls: 141.4 cm
Girls having heights more that the mean height: 5 girls
Step-by-step explanation:
Range of data= Maximum Value- Minimum Value
= 151-128
=23 cm
Mean height of the girls= 135+150+139+128+151+132+146+149+143+141/ 10
