### Scenario 2: Plant Key Innovations Some genera have far more species than others. Is this just luck, or have some genera hit upon a "key innovation" that gives them a benefit and allows more species to accumulate? One possible key innovation in plants is the ability to climb like a vine, which makes it possible to reach above other plants to compete for light. A study counted the number of species in 48 randomly selected genera that had all evolved climbing (Gianoli 2004). For each of those genera, the researchers also found the most closely related non-climbing genus and counted the number of species in each. (The two genera belong to the same family taxonomically, and would not be considered independent.)The number of species from each of the climbing non-climbing genera are recorded in plant_evolvegenera.csv. Define the difference as minus Non.climbing 2.1. State the research question . 2.2. State the parameter of interest 2.3. State the null and alternative hypotheses in symbolic and sentence form. 2.4. What type of test is appropriate for this analysis ? Justify your response . 2.5. Assess the conditions for conducting the appropriate test in the context of the problem . You may need to run code to get some of the answers , but all answers need a justification , including references to any code that helped you . Insert code chunk here > > 2.6.
