Three students test the effect of fertilizer on bean plant growth. Each student conducts one trial. They plant 10 beans in each of 3 large pots of soil with different amounts of fertilizer. After 2 weeks, they measure the heights of the plants in each pot. Then they find the average height for each amount of fertilizer. The table summarizes the results of the experiment.

• The data from Trial 1 are inconsistent with the data from Trials 2 & 3.

• The data for the average heights of plants in all 3 trials contain erros.

• The trend in the data for trial 1 shows that plants grow taller if given more fertilizer.

• The trend in the data for trial 2 shows that more fertilizer causes less growth.
