with written work 

When morphine is injected, it typically causes decreased motor activity.
However, we develop a tolerance to morphine with repeated dosages, so a
greater dosage is needed to produce the same effect. We are testing a new
drug, Bloomingtine which may not have the same tolerance characteristics.
We inject the same 5 rats with the same dosage of Bloomingtine every day
for 4 days, and measure their motor activity. Go through the steps of
hypothesis testing to determine if motor activity changes over the 4
different days (set a = .05). The data follow (higher numbers indicate greater
activity).
