o determine whether talking to plants affects their health, a researcher conducts a study in which he talks to one group of five plants and does not talk to the second group of five plants. After two weeks, he records the number of blooms produced by each plant (the dependent measure of their health). The researcher finds that, on average, the five plants he talked to produced 4.3 blooms (SD = 2.2), while the five plants he did not talk to produced 3.2 blooms (SD = 2.0). (a) Perform an independent-samples t-test to determine whether talking to the plants significantly affected their health.
