Step-by-step explanation:
mean:
1. 29 + 34 + 37 + 22 + 15 + 38 +40 = 215
215 ÷ 7 = 30.71
2. 5 + 6 + 7 + 7 + 9 + 9 + 10 + 14 + 16 + 20 = 103
103 ÷ 10 = 10.3
3. 82 + 61 + 93 + 56 + 34 + 57 + 92 + 53 + 57 = 585
585 ÷ 9 = 65
4. 26 + 32 + 12 + 18 + 11 + 12 + 15 + 18 + 21 = 153
153 ÷ 9 = 17
5. 25 + 33 + 35 + 45 + 34 + 26 + 29 + 35 + 38 + 40 = 340
340 ÷ 10 = 34
median:
1. 15, 22, 29, 34, 37, 38, 40
(7 + 1) ÷ 2 = 8 ÷ 2 = 4
2. 5, 6, 7, 7, 9, 9, 10, 14, 16, 20
(10 + 1) ÷ 2 = 11 ÷ 2 = 5.5
9 + 9 = 18 ÷ 2 = 9
3. 34, 53, 56, 57, 57, 61, 82, 92, 93
(9 + 1) ÷ 2 = 10 ÷ 2 = 5
4. 11, 12, 12, 15, 18, 18, 21, 26, 32
(9 + 1) ÷ 2 = 10 ÷ 2 = 5
5. 25, 26, 29, 33, 34, 35, 35, 38, 40, 45
(10 + 1) ÷ 2 = 11 ÷ 2 = 5.5
34 + 35 = 69 ÷ 2 = 34.5
mode:
1. 15, 22, 29, 34, 37, 38, 40
none (there is no repetition number)
2. 5, 6, 7, 7, 9, 9, 10, 14, 16, 20
7 + 9 = 16 ÷ 2 = 8
3. 34, 53, 56, 57, 57, 61, 82, 92, 93
4. 11, 12, 12, 15, 18, 18, 21, 26, 32
12 + 18 = 30 ÷ 2 = 15
5. 25, 26, 29, 33, 34, 35, 35, 38, 40, 45
