Null Hypothesis:
The percent change in inflation of end of period consumer prices from 1980-2010 in each individual country that revolted is equal to the inflation of all the other countries that revolted in from 2010-2011.
Alternative Hypothesis:
The percent change in inflation of end of period consumer prices from 1980-2010 in each individual country that revolted is equal to the inflation of all the other countries that revolted from 2010-2011.

Summary of Data of countries that revolted:
Mean: 9.38% increase in inflation from 1980-2010
StDev: 6.48
Range:17.10%
Max:18.91% increase in inflation from 1980-2010
Min:1.82% increase in inflation from 1980-2010

Method of Data Analysis: 2-Sample T-Test
Conditions
It can be assumed that the measure of inflation of each individual country's inflation is independent. Each country's measure of inflation was compared individually to every other country.
The distribution for average inflation rates from 1980-2010 is approximatley normal.
degrees of freedom=n-1
number of years assesed=30
df=29

Significance level: t=.5
Significance level in context: I would fail to reject the null hypothesis that the the percent change in inflation of end of period consumer prices from 1980-2010 in each individual country that revolted is equal to the inflation of all the other countries that revolted in the past year if the probability of this situation occuring is greater than 50%.

How to interpret this picture:

The only situation in which I would fail to reject the null hypothesis that the percent change in inflation of end of period consumer prices from 1980-2010 in each individual country that revolted is equal to the inflation of all the other countries that revolted in from 2010-201 is when comparing the inflation of Jordan and Libya, because the probability that these two samples are equal is 71%. It is important to note that in all other cases, I would reject the null hypothesis because the probability that the inflation rates of each Middle Eastern country that revolted (other than Jordan and Libya) are equal is less than %50.

Link to other Middle Eastern Countries: There is a greater probability that Bahrain's inflation as a percent change in end of period consumer prices is more similar to that of Oman than any of the countries that experienced a mass level of protest like Bahrain. This pattern is evident in Tunisia, Lybia, Jordan and Syria.
