The Interdisciplinary Laboratory

 Pre-Lab Assignment #2 for Experiment #2:
Carbonate Content of Biological Hard Tissue

Samples of hard tissue containing carbonate have been analyzed with the results given below.

Sample A (%wt carbonate): 87.8, 90.2, 87.2

Sample B (%wt carbonate): 92.4, 90.3, 94.0

Sample C (%wt carbonate): 88.7, 93.3, 92.2

To a 95% confidence level, are these samples statistically different from each other in their carbonate content?

Submit your responses via e-mail to Professor Van Hecke (Gerald_VanHecke@hmc.edu) by 7 p.m. on the Monday evening prior to your second laboratory day (i.e., Monday,  15 September or Monday, 13 October). Bring a printed copy of your calculations supporting your answers to turn in at the start of your second laboratory period.
