Answer:
(a) 23, 35, 28, 33, 5, 12, 40, 25, 20, 18, 1, 16
1, 5, 12, 16, 18, 20 23, 25, 28, 33, 35, 40
n = 12 M = (20 + 23)/ 2 = 21.5
Q1 = (12 + 16) / 2 = 14 Q3 = (28 + 33) /2 = 30.5
(b) 22, 33, 25, 28, 5, 12, 35, 23, 20, 18, 1, 40, 16
1, 5, 12, 16, 18, 20 | 22 | 23, 25, 28, 33, 35, 40
n = 13 M = 22 Q1 = 14 Q3 = 30.5
(c) 20, 28, 23, 25, 3, 5, 33, 22, 18, 16, 40, 1, 35, 12
1, 3, 5, 12, 16, 18, 20, 22, 23, 25, 28, 33, 35, 40
n = 14 M = (20 + 22)/2 = 21 Q1 = 12 Q3 = 28
(d) 20, 28, 23, 25, 3, 5, 30, 22, 18, 40, 16, 35, 1, 33, 12
1, 3, 5, 12, 16, 18, 20 | 22 | 23, 25, 28, 30, 33, 35, 40
n = 15 M = 22 Q1 = 12 Q3 = 30
hope this helps :)
