Answer 2

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 = \frac{Sum\ of\ all\ heights}{Number\ of\ girls}

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

= 141.4 cm

v) Number of girls having more height than the mean height

= 5 girls.
