Using Base R Dataset PlantGrowth

1. How would I conduct an appropriate significance test on the PlantGrowth dataset? And what would be the R code and output?

2. a) I also need to firstly discuss the underlying assumptions needed to conduct the analysis above.

b) And also I need to provide evidence to support the validity of the procedure, providing R code and output with discussions.

3. An open question, if I were to collect the PlantGrowth data, what would I try to do to minimize confounding?
