It was felt that, a compositional analysis, as opposed to a dimensional one, would produce a more consistent correlation to the strength of chicken bone. A study involving a colorimetric and gravimetric analysis of calcium concentration appeared to be a viable approach for an extension on the above experiment..
There are two objectives for the proposed laboratory experiment. The first of these will be to analyze the effect of calcium content on the fracture energy of chicken bones. Additionally, since two methods for calcium content determination will be employed, the second objective will be to examine the precision between the two aforementioned analytical methods.
The primary hypothesis, corresponding to the primary objective, is that calcium concentration will significantly correlate to fracture energy in chicken bones in each of the two cases. This will be tested via a regression analysis on JMPIN 4 statistical software, with a significance restriction of p<0.05 on each of the slope parameters for calcium concentration. In view of the second objective, it is also hypothesized that both analytical methods will provide a statistically equivalent finding on correlation of calcium content to fracture. This will be demonstrated through a two-tailed t-test (with a significance of p<0.05) between the slope parameters determined from the regression analyses above.
