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.
