The Transfer of Bacteria to the Points of Entry on the Face

The purpose of our experiment was to test to see if two groups of data are from the same population. One group received a treatment that was a lecture on the transfer of bacteria and the importance of washing hands for the removal of these bacteria. The test subjects were unknowingly exposed to a bacteria simulated solution via their hands. After one hour each subject was tested for the transfer of bacteria from their hands to their face. We measured the distances, in centimeters, of the bacteria from the three points of entry on the face. For our analysis we ran two-sample t-tests from the averages on each data set from the points of entry. Our null hypothesis is that the two data sets came from the same population. After running the analysis on the data, we failed to reject our null hypothesis.
