Given : The experiment shows that the average monthly electricity consumption for a house is 458 units.
The study records a total of 3206 units of electricity consumption.
To find : Duration of the experiment.
the criteria to calculate the median consumption.
Solution:
average monthly electricity consumption for a house is 458 units.
Let say duration = n months
Hence total consumption = 458n units
Total Consumption = 3206 units
Equating both
=> 458n = 3206
=> n = 7
Hence duration was 7 months
criteria to calculate the median consumption. :
arrange all the monthly consumptions in order
and consumption at 4th number will given the median consumption
