The experimental units are what you apply the treatments to. In this experiment it would be the subjects or the customers in this situation since they will be treatment (either standing at their regular height or squatting to meet the eye level which could affect the amount of tip they give). An example of randomization can be numbering each table in the restaurant and picking them out of a hat and going to that table that you randomly chose and imposing the treatment on the customers there. Because tips depend on the income of the customers and how much they are willing to give for their meal. If not even income some people are willing to give despite how much money they make so their tips may higher than the wealthy crowd.

A phylogenetic tree is also called an evolutionary tree and it shows the evolutionary relationships that exists among organisms called taxa based on their physical or genetic similarities and differences. The Phylogenetic tree consists of ingroup and outgroup. The ingroup consists of a group of closely related organisms or taxon while the outgroup represents a more distantly related group of organisms or taxon but as close as possible to the ingroup.
The Lily represents the outgroup in the phylogenetic tree while the Orchid are the ingroup. This is because the Lily is distantly related to the orchid.
