Answer:
i) Height of tallest girl = 151 cm
ii) Height of shortest girl = 128 cm
iii) Range = Height of tallest girl - shortest girl
iv) Mean height = (Sum of all heights)/(Number of girls)
=
135 + 150 + 139 + 128 + 151 + 132 + 146 + 149 + 143 + 141/10
= 1414/10
= 141.4 cm
v) Number of girls having more height than the mean height
= 5 girls
