Experiment Rats: Are They Right Or Wrong?

Discussion Since the experiment is now over I can see whether or not my hypotheses were right or wrong and whether or not the P-Value accepts or rejects the null hypothesis. I predicted that the control group would have the higher average body weight than the experimental rats, in this case my hypothesis was correct. Because the experimental rat was an adolescent it showed different symptoms than the adult rat. If the adult rat had hypothyroidism then they would gain weight, but because the experimental rat was an adolescent rat with hypothyroidism it did not gain weight. Therefore, the control group had a higher average body weight. The P-Value for this also fails to reject the null hypothesis. My other prediction was that the experimental rat will have a higher metabolic rate, this hypothesis …show more content…
When I looked at the data results and the graphs it shows that the control group had a higher metabolic rate. The P-Value for this hypothesis rejects the null hypothesis and is the only significant P-Value. My next prediction was the experimental rat would have the higher testis weight and this hypothesis was correct. The experimental rate had hormone injected causing the testis to grow and become bigger than the average size. My last prediction was that the thyroid weight would be higher in the experimental rat and that hypothesis was correct as well. The testis and thyroid weight was higher in the experimental rat because thyroid hormone regulates growth, development and metabolism in tissues causing the testis and thyroid to grow. In the case with the metabolic rate, the symptoms are different in adults and adolescents so the thyroid hormone did no speed up the metabolic rate in the experimental rat. Again, the P-Value fails to
