A farmer plants tomato seeds into four different plots. In each plot, there is a different fertilizer treatment that is applied to the soil. After conducting the hypothesis test for the mean heights, he obtains Tukey's confidence intervals which are below. Use Tukey's confidence intervals to determine which plots/fertilizers have different mean heights.
