PROBLEM :

Two samples of rats are timed for their maze running time. One group is taking a drug and the other is not. The times are given in the following table:

Rats with drug       Rats w/o drug

      15                     11

      12                     13

     13                       9

     12                       6

     10                     11

     11

Determine whether the use of the test drug results in a different maze running time. Use the .05 level of significance.
