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. Question: How should the alternative hypothesis be stated?
