ANSWER:
1. Mean:
1.2 + 2.3 + 4.5 + 2.0 + 1.5 + 1.6 + 5.0 + 5.5 + 5.7 ÷ 9
= 29.3 ÷ 9
= 32.5
Median:
= (2.0 + 1.5) ÷ 2
= 3.5 ÷ 2
= 1.75
Mode:
0
2. Mean:
10 + 12 + 14 + 10 + 15 + 18 + 20 + 20 + 20 + 21 ÷ 10
= 160 ÷ 10
= 16
= (15 + 18) ÷ 2
= 33 ÷ 2
= 16.5
10 and 20
3. Mean:
85 + 84 + 85 + 87 + 88 + 85 + 52 + 89 + 88 + 86 + 87 + 82 + 83 + 8 + 4 + 80 ÷ 16
= 1,173 ÷ 16
= 73.3
= (85 + 52) ÷ 2
= 137 ÷ 2
= 68.5
