Extracted text: 6. You and your friend each get graded by judges on a long figure skating program. You each get randomly assigned to a different group of judges (group A or group B). You get Group A and score a 8.4 out of 10 possible points. Your friend gets Group B and scores 9.2 out of 10 possible points. The judges scores are normally distributed with the following means and standard deviations Group A: mean=6.2, s.d.=1.4 Group B: mean =7.4, s.d.=2.8 Give a more complete explanation of how you each did compared to each other based on what you learned in Chapter 6 beyond just each of your scores. (2-3 sentences with numerical evidence included).
