In a herd of 15 horses, a veterinary anatomist measured the density of nerve cells at one of two different sites in the intestinal tissue. She wants to see if there is a difference in nerve cell density between the two different sites. Her results from the two sites are listed below.
Site I: 50.6, 38.2, 35.2, 17.0, 11.2, 24.2, 37.4, 35.2
Site II: 38.0, 18.6, 23.2, 19.0, 6.6, 14.4, 16.4
a. What assumptions would you have to check to determine if the two sites significantly differed in nerve density?
b. Carry out the appropriate hypothesis test to answer the question in part 1a. Be sure to include all steps and show your work to receive full credit. Assume your assumptions have been met.
c. If the vet had tested 200 different horses for her study, what hypothesis test would she have potentially used to answer the same question? What assumptions would she have to check before running that test?
