\subsection{Shooting Time vs. Distance}
A students-t test with a 0.05 significance level conducted on the shooting time data at the three distances from the target and confirmed that the mean shooting time was comparable at all three ranges and invariant as a result of distance.
The null hypothesis claiming an even distribution in shooting time was therefore confirmed.
\subsubsection{10m to 20m}
An F-test was conducted and it was found that the P-value was greater than the alpha-significance level of 0.05, correlating with equal variances.
A paired t-test was conducted because the same of people participated at 10 and 20m, and the P-value was found to be
greater less than the significance level. The means are therefore unequal, shooting time was faster at 20m. The alternate hypothesis was therefore accepted over the null hypothesis.
\subsubsection{20m to 30m}
Using an F-test it was found that the P-value was greater than the significance level, therfore the variances within the two data sets were found to be the same.
Participants did not all fire at 20m and 30m, therefore a two-sample t-test was used instead of a paired t-test.
It was found that the P-value was greater than the significance level,
therefore corresponding with equal means. This means that shooting time was the same at both distances. The result is fail to reject the null hypothesis.
