Ammonium Sulfate Lab Report

The mean data observed show a number of trends. The average weight and length tend to decrease as the amount of Ammonium Sulfate approaches the full recommended dose. On the other hand, the average amount of protein per gram of tissue tends to increase as the amount of Ammonium Sulfate approaches the full recommended dose.

Our null hypothesis was that there is no difference between the mean weights or the mean lengths of the seedlings two different treatments. (A+B, A+C, and B+C) Each of these null hypotheses was tested using an alpha-value of 0.05. A rejection of the null hypothesis means that the two mean values in question have been determined to be different with ninety-five percent certainty.

The standard curve in Graph One was used to determine the protein concentration
In our calculation of the various two-sample test statistics, the data showed that in both weight and length, the difference in mean values between each Ammonium Sulfate treatment and the Roundup control is statistically significant with an alpha-value of 0.05. In every case, the length and weight of the seedlings in treatment A was found to be greater than that of the seedlings in treatments B or C, as predicted. The only case in which the difference between two means was not statistically significant was the weight difference between treatments B and C. This means that it would be risky to make a statement as to the benefit of using the full dose of Ammonium Sulfate over a half-dose. Because the difference in lengths between treatments B and C was statistically significant, it is quite possible that there is a statistically significant difference in seedling health between the half-dose and the full dose of Ammonium Sulfate, but the relationship is tenuous at best. More research would be needed to clarify the results between treatments B and
