Answer:

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is 7,739.5 Megawatts.

Explanation:

Electricity generated in Texas by wind powered turbines:

In 2007 : 4,353 Mw

In 2008 : 7,113 Mw

In 2009 : 9,403 Mw

In 2010 : 10,089 Mw

$Mean=\frac{\text{sum all observations}}{\text{total number of observations}}$

$\text{Mean amount of electricity from 2007 to 2010}:$

=(4,353+7,113+9,403+10,089)/(4)=(30,958)/(4)=7,739.5

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is 7,739.5 Megawatts.

Answer:

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is 7739.5.

Explanation:

From the given table it is noticed that the electricity generated in Texas by wind powered turbines from 2007 to 2010 are 4353, 7113, 9403 and 10089.

Formula of mean:

$Mean=\frac{\text{Sum of observations}}{\text{Number of observations}}$

The sum of wind powered turbines from 2007 to 2010 is

S=4353+7113+9403+10089=30958

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is

Mean=(30958)/(4)=7739.5

Therefore the mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is 7739.5.
