Hi, this is for my zoology class and it is a scientific paper on optimal forging. This is the data from the degree of calculation. At high, the feed was 184cm and at low, it was 110cm. The formula is Observed plus the Expected square divided by the Expected. The Obvs. is 110, the Exp. is 147. (obvs. + exp.)2 / exp. At the degree of freedom .25 is 1.8, at .10 is 2.3, at .05 is 3.84, and at .05 is 6.64, at .01 is 7.88, and at .001 is 10.83. This is from the degree of freedom.

In the result- There was a significant difference in high or low feed. Make a graft to show the high and low percent of the food that was consumed by the birds. Look at some scientific papers- peer review on scientific papers.
