Fertilizing bromeliads. Bromeliads are tropical flowering plants. Many are epiphytes that attach to trees and obtain moisture and nutrients from air and rain. Their leaf bases form cups that collect water and are home to the larvae of many insects. As a preliminary to a study of changes in the nutrient cycle, Jacqueline Ngai and Diane Srivastava examined the effects of adding nitrogen, phosphorus, or both to the cups. They randomly assigned 8 bromeliads growing in Costa Rica to each of four treatment groups, including an unfertilized control group. A monkey destroyed one of the plants in the control group, leaving 7 bromeliads in that group. Here are the numbers of new leaves on each plant over the seven months following fertilization: Nitrogen Phosphorus Both Neither 14 14 11 14 14 16 13 15 14 15 16 16 11 14 15 17 13 14 15 18 12 15 13 17 14 11 a) What are the null and altemative hypotheses for this test? 17 12 13 15 Null Hypothesis Altenative Hypothesis b) Does nitrogen or phosphorus have a greater effect on the growth of bromeliads?

Most vertebrate adult body sizes remain constant or increase throughout their lives. Marine iguanas are different in that they can actually decrease in size, in periods of low food availability. Examine the data set here, and test the hypothesis that on average across time, iguana length changed (increased) by 1 mm. Paste your R code in the answer box, and tell me your conclusion.
