Question

14.(6 pts) Use this data set of clutch size (eggs/nest) data to answer the following. 1, 1, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 5, 16, 17 a) Range: b) Interquartile range: c) Mode: 15. (9 pts.) In an experiment a freshmen biology major conducted an experiment to determine which plant (spinach versus mustard greens) was more efficient in utilizing light for the photochemical reaction of photosynthesis. The student placed degassed leaf disks into a 0.1% NaHCO3 solution and exposed the leaf disk to different concentrations of light (measured as µE/m²/s). After a few minutes, the leaf disks started to float because of O2 production. She measures the time for each leaf disk to float and average the times. To graph her results, she the calculated the reciprocal mean float time. The data table and graph are below.
