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.
