Probability = is a way to measure the chances
that something occur in relation to the possible
alternatives

Variance and standard deviation
 Variance and standard deviation are two values that
are used in statistics to describe how far away your
data are from the mean

Theoretical Distribution
The chi square test can be used to see there if there are
any significant differences between data site or sources
Yes, the fishers should reject the null hypothesis
because there t-statistic value was calculated to
be 3.75 which is greater than the critical value of
2.145 from the t-statistic table at value at 14
degrees of freedom and at the p-value of 0.05.
