Chicken Liver Hypothesis

Experimental Design
Research Question: Does the rate of reaction (mL/sec) for the enzyme catalase differ in endotherms versus ectotherms?
Alternative Hypothesis 1: If the enzyme catalase reacts, then the rate of reaction for the endotherms will have a consistent reaction rate because the endotherms produce more heat for the enzyme to operate efficiently.
Alternative Hypothesis 2: If the enzyme catalase reacts, then the rate of reaction for the ectotherms will have a lower reaction rate than the endotherms because the ectotherm body temperature rises and falls to the temperature of the environment.
Null Hypothesis: If the enzyme catalase reacts, then there is no statistical difference between the rate of reaction of endotherms and ectotherms.

If the p-value is greater than .05, then the null hypothesis would be rejected. The null hypothesis was rejected because the p-value was less than 0.05, it was 0.02. The trends in the data that occurred was the averages of the Chicken Liver (Endotherm) had a higher rate of reaction with 7.90 mL/sec, while the Perch Liver (Ectotherm) had a lower rate of reaction with 6.05 mL/sec. Therefore, the endotherm had higher data points, while the ectotherm had lower data points showing that the endotherm rate of reaction is faster. Variance the measure of variability, which is the spread of the data. The variance for Chicken Liver (Endotherm) is 9.11 mL/sec and Perch Liver (Ectotherm) is 2.14 mL/sec. Since variation shows how close the data points compare to the mean, the endotherm has a larger difference between the variance and the mean than the ectotherm, which shows that the endotherm has less precision in the number set. The trends in the standard deviation of the Chicken Liver (Endotherm) is 3.82 mL/sec and the Perch Liver (Ectotherm) is 1.46 mL/sec. A high standard deviation shows that the data is less reliable since the data is widely spread and a low standard deviation shows that the data are more reliable since the data is closer to the mean.

The null hypothesis is rejected since the p-value fell below .05, with .02 therefore there is a statistical difference between the rate of reaction of an enzyme in an ectotherm and endotherm. The data supports the claim since the ectoderm has a lower reaction rate than the endotherms because the ectotherm body temperature rises and falls to the temperature of the environment (Ecto- versus endothermic organisms, 2016). The reason for this is because the endotherm had a higher rate of reaction with 7.90 mL/sec, while ectotherm had a lower rate of reaction with 6.05 mL/sec. Therefore, the endotherm had higher data points, while the ectotherm had lower data points showing that the endotherm rate of reaction is faster. The alternate hypothesis number one was rejected. The alternate hypothesis number one was “If the enzyme reacts, then the rate of reaction for the endotherms will have a consistent reaction rate because the endotherms produce more heat for the enzyme to operate efficiently.” Although the endotherms do produce more heat for the enzyme to react, the rate of reaction does not remain consistent with the same reaction rate throughout the experiment. The average rate of reaction for the endotherms was 7.90 mL/sec and the endotherm had a higher standard deviation which shows it less reliable since the data points are spread unevenly. The standard
