You would like to know whether there is a difference between the rate of cooling of freshly killed corpses versus those that were reheated (to determine if you could fool a coroner about time of death). You tested several rats for their cooling constant, both when the rat was freshly killed and after the same rat was reheated. Assuming the distribution of differences is normal, is there any difference in the cooling constants between freshly killed and reheated rats?

Use the data set on corpses. Test the same hypothesis as the previous question, but this time assume that the differences are not distributed normally.

RAT: mean=10.0; n=19; SD= 5.6273

FRESHLY KILLED: mean= 417.9; n=19; SD=59.496

REHEATED: mean=381.3; n=19; SD=78.522
