Answer 1

Answer:

10,11,11,12,13,13,14,16,16,17,17,18

median = (13 + 14)/2 = 13.5

mean =

12

10+11+11+12+13+13+14+16+16+17+17+18

mean = 14

mean deviation = 14-13.5 = 0.5

2) 36,42,45,46,46,49,51,53,60,72

median = (46+49)/2 = 47.5

mean=

10

36+42+45+46+46+49+51+53+60+72

mean = 50

mean deviation = 50-47.5 = 2.5
