An indigenous plant is used by natives to help those with anxiety. It is believed by natives to immediately reduce anxiety. A study was conducted to test the actual effects of this plant. Participants were given different amounts of the plant extract after being placed in a high anxiety situation. Anxiety scores were then measured. The higher the score, the more anxiety the participants were experiencing. Due to the lack of research surrounding this plant, researchers did not have formal hypotheses. Therefore, compare all 3 groups if the null hypothesis is rejected. Use alpha = .05. Control I ounce 2 ounces - 17 ss, = 234 SS, = 206 SS, = 328 n, = 30 n, - 30 n, - 30 - 19 - 13 Total
