Using the below dataset test the difference between the control group and treatment 2 on mean agricultural yields. Set 10% risk of type I error.

1. How would I conduct an appropriate significance test for these data? Provide the R code and output.

2. a) Discuss the underlying assumptions needed to conduct the analysis above.

b) Provide evidence to support the validity of the procedure, including R code and output with discussions.

3. How could confounding be minimized in the design of this experiment?
