A second semester class is studying the environment. One of the assignments is to grow bean plants in different soils. Ahmad chose to grow his bean plants in soil found outside his classroom mixed with dryer lint. Wong chose to grow her bean plants in potting soil bought at the local nursery. Lethmi chose to grow his bean plants in soil from his mother's garden. They were grown inside the classroom next to a large window. At the end of the growing period, each plant was measured, producing the data (in cm).
