You decide to conduct your own studies using an independent-samples (between-subjects) design, to determine if a cherry vs. blueberry supplement can change cognitive capacity in older adults. You will use an alpha level = .05, and conduct a two-tail test (you don't know if the supplement will make them better or worse). You choose to examine 16 adults who are between the ages of 65 and 75, and measure they cognitive capacity using a standardized test. Participants receive either a cherry or blueberry supplement that they drink every day for 30 days. Cognitive capacity is measured at the end the experiment (higher scores mean better cognitive capacity). The data for each condition is below: Cognitive Capacity with Cherry Supplement Cognitive Capacity with Blueberry Supplement P1 =70 P9 = 78 P2 = 64 P10 = 69 P3 = 64 P11 = 71 P4 = 71 P12 = 80 P5 = 76 P13 = 77 P6 = 75 P14 = 75 P7 = 82 P15 = 88 P8 = 69 P16 = 74 Answer the following: 1.
