Answer:
In this experiment, six samples of Brandywine were taken from a shaded environment and six samples were taken from a direct sunlight environment. The results showed that there was not much photosynthesis happening in the sunlight environment. This may have been caused by a drop in weather during the experiment, which resulted in the chloroplasts in the leaves dying. For the shaded environment, there was more respiration than photosynthesis happening in the leaves. The t-values for NPP, GPP, and R were all larger than 0.05, so the null hypothesis was rejected. The P value was also smaller than 0.05, indicating that the null hypothesis should be rejected. However, due to weather complications, the data and results cannot definitively say whether there was a difference in GPP between the two plants in different environments.
