This can be re-written as
From the table
This can be done for .
However to obtain the value of
Mean value of
is the margin of error
Taking critical value to be then
Substituting the parameter values in the equation
Lets assume , then
Figure 1: Box plot of outdoor temperatures
Figure 2: Box plot of average wind speed
Figure 3: Box plot of kWH
The higher the outdoor temperature, the higher the average wind speed and the lower electricity use. This is related since during the higher temperatures more energy is needed to cool the surrounding residence. However, higher wind speed aides in cooling the residence, hence higher energy will not be needed to cool the residence as the temperatures are lowered by wind. This leads to low energy consumed in terms of electricity use. Therefore, as the wind speed and temperature increases, electricity use reduces.
