A:
Answer:Emma ⇒ IQR = 3.5Sally ⇒ IQR = 3Olivia ⇒ IQR = 2.5Emma - Sally - OliviaStep-by-step explanation:Emma's Scores:6 , 7 , 8 , 8 , 9 , 9 , 9 , 10 , 10 , 11 , 11 , 11 , 11 , 11 , 12 , 13 , 13 , 13 , 13 , 14LQ = (9 + 9) ÷ 2 = 9UQ = (12 + 13) ÷ 2 = 12.5IQR = 12.5 - 9 = 3.5Sally's Scores:6 , 6 , 6 , 7 , 7 , 8 , 8 , 8 , 9 , 9 , 10 , 10 , 10 , 10 , 10 , 10 , 11 , 11 , 12 , 12 , 14 LQ = (7 + 8) ÷ 2 = 7.5UQ = (10 + 11) ÷ 2 = 10.5IQR = 10.5 - 7.5 = 3Olivia's Scores:6 , 6 , 7 , 7 , 7 , 8 , 8 , 8 , 8 , 9 , 9 , 9 , 9 , 9 , 10 , 10 , 12 , 12 , 13 , 14LQ = (7 + 8) ÷ 2 = 7.5UQ = (10 + 10) ÷ 2 = 10IQR = 10 - 7.5 = 2.5Emma - Sally - Olivia
