Answers
Answer:
1. 4.5
2. 10
3. 6
4. 7
5. 20
6. 7
Step-by-step explanation:
1.arithmetic mean = sum of all observations ÷ total number of observations
=1+2+3+4+5+6+7+8/8
=36/8
=4.5
2. arithmetic mean=1+3+5+7+9+11+13+15+17+19/10
= 100/10
= 10
3.arithmetic mean =2+4+6+8+10/5
=30/5
=6
4. arithmetic mean
=2+4+6+8+10+12/6
=42/6
=7
5. arithmetic mean
= 5+10+15+20+25+30+35/7
= 140/7
= 20
6. arithmetic mean
= 1+2+4+5+10+20/6
= 42/6
= 7
