Answer the given questions based on the following problem.

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

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 null hypothesis be stated?
The test drug results of the rats who were given drugs test drug
results of the rats who were not given drugs.
