Question

Solve the following numerical problem.

The rainfall in a city on each day of a week is recorded below. Find the average rainfall for the week.

day	Mon	Tue	Wed	Thurs	Fri	Sat	Sun
Rainfall (in mm)	1.2	10.3	5.5	0.0	13.5	7.0	1.0

Answer 1

The sum of recorded rain fall
1.2 mm + 10.3 mm + 5.5 mm+ 13.5 mm + 7 mm+ 1mm = 38.5 mm
Number of days = 7
Average rainfall of the week = sum of all observations / number of days
= 38.5 / 7 mm = 5.5 mm
