ii) Height of shortest girl = 128 cm
iii) Range = Height of tallest girl - shortest girl
iv) Mean height = \frac{Sum\ of\ all\ heights}{Number\ of\ girls}
Number of girls
Sum of all heights
= \frac{135\ +\ 150\ +\ 139\ +\ 128\ +\ 151\ +\ 132\ +\ 146\ +\ 149\ +\ 143\ +\ 141}{10}\ =\ \frac{1414}{10}
10
135 + 150 + 139 + 128 + 151 + 132 + 146 + 149 + 143 + 141
=
