The college physical education department offered an advanced first aid course last semester. The scores of the comprehensive final exam were normally distributed and the z scores for some of the students are shown below: Robert: 1.10 Joel: 0.00 Juan: 1.70 Jan: -0.80 Susan: -2.00 Linda: 1.60 a.) Which of these students scored above the mean? b.) Which of these students scored on the mean? c.) Which of these students scored below the mean I need an explaination of how to get the answers, please! Solution The meanof the scores = (1.10 + 0.00 + 1.70 -0.80 -2.00 + 1.60 ) / 6 = 0.255 So, above mean = Robert, Linda, Juan Below mean:, Susan, Joel,Jan mean = no one..
