Ali hypothesized that increasing fertilizer would increase plant growth. Four groups of thirty similar plants were given 0 to 15 ml of fertilizer, as shown in the graph. The change in plant height for each group over a two-week period was averaged and recorded. Plant Group Fertilizer Added (mL) Avg. Growth (cm) A 0 4 B 5 6 C 10 8 D 15 3 What is the best conclusion based on this data? The hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. The hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. The hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. The hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
