Question #N94

A group of scientists conducted a study to determine if a new type of fertilizer increased crop yields. They planted a specific type of fruit tree in two different plots of land. One plot was treated with the new fertilizer, while the other plot was treated with a standard fertilizer. After several months, the scientists measured the height of each fruit tree in both plots. They found that the fruit trees in the plot that was treated with the new fertilizer had a higher average height than the trees in the control plot, which was treated with the standard fertilizer.
