Solutions

      Although it was difficult to distinguish the substances because the data for each solution was all over the place , I found that solution A was the stimulator , solution B was the depressant , and solution C was the water. I determined this by counting how many 30's and 40's were found in each category because they seemed to be recorded the most. The numbers were close but they showed a clear difference . Solution A had twenty seven 30's and twenty two 40's while solution B had twenty one 30's and fourteen 40's . Solution C had twenty two 30's and eighteen 40's.  Thus supporting the inference that A has the highest number of heartbeats, B has the least number , and C is in between.
