Answer:
i) Range = Maximum value - minimum value
= maximum rainfall - minimum rainfall
= 20.5 - 0.0
= 20.5mm
ii) Mean rainfall
= \frac{sum\ of\ rain\ fall\ \left(in\ mm\right)}{Number\ of\ days}\
Number of days
sum of rain fall (in mm)
= \ \frac{0.0\ +\ 12.2\ +\ 2.1\ +\ 0.0\ +\ 20.5\ +\ 5.5\ +\ 1.0}{7}\ =\ \frac{41.3}{7}mm
7
0.0 + 12.2 + 2.1 + 0.0 + 20.5 + 5.5 + 1.0
=
7
41.3
mm
= 5.9mm
iii) Number of days on which rainfall was less than the mean rainfall
= Monday, Wednesday, Thursday, Saturday, Sunday
i.e. 5 days.
