Researchers set up an experiment in which they treat plants with a new fertilizer and compare plant height after 2 months to a control (untreated) group of plants. Using the data that follow, perform a t-test (α = 0.05) to determine whether the fertilizer affected plant height in this experiment. Use this formula:
