13. A researcher designed an experiment to explore the growth of a plant species with C4 photosynthesis that is salt tolerant. Four levels of salt concentration were of interest to the researcher: 0, 50, 100 and 200 mM NaCl. The experiment consisted of 16 tubes identically planted to the plant species and then randomly assigned to the four salt treatments (4 replicate tubes per treatment). The tubes were placed in individual hydroponic growth systems at the specified concentration of NaCl in the water and the plants were allowed to grow for 8 weeks. At the end of the growth period, the plants were harvested and the dry weight of the roots was measured.
