For the Following questions use Dataset 4.1 below.

1. The following experiment aimed to test the effect of Fluoxetine on a rodent anxiety test the open field test. In the test, lower amounts of time spent in the open and or increased time spent in the corners corresponds to higher levels of anxiety. Report the p value of the t-tests looking at the differences between Fluoxetine and Vehicle in the reported test measures:

2. Generate bar plots for all three of these measures. Ensure all graphs are in the proper scale.

3. What are your conclusions from this study? Did the drugFluoxetine increase or decrease anxiety in any way? Explain using p-values.
