n¡ 3. It has been proposed that mindfulness meditation will improve spatial reasoning abilities and that the more mindfulness meditation a person engages in, the better will their spatial reasoning ability be. To test whether this is true, people are randomly assigned to one of three groups, which each day engage in either 30 minutes, 60 minutes, or 120 minutes of mindfulness meditation for 4 weeks. After 4 weeks, the participants are given a test of spatial reasoning ability and the following summary statistics were obtained (higher scores = better spatial ability): X-bar 21.2 S₁ 30 minutes minutes 5 2.88 60 minutes 120 5 5 10.4 13.0 2.74 3.03 Is the prediction that the more mindfulness meditation a person engages in the better their spatial ability will be supported by the data (alpha = .05)?
