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 GroupFertilizer Added (mL)Avg. Growth (cm)A04B56C108D153What is the best conclusion based on this data?
A
The hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth.B
The hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant.C
The hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth.D
The hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
