Answer:
1: 9
2: 25.75
Step-by-step explanation:
Question 1:
1. Set up the equation to find the mean.
- [tex]\frac{12+8+7+10+8+8+10}{7}[/tex]
2. (Solving)
- [tex]\frac{12+8+7+10+8+8+10}{7}[/tex]
- [tex]\frac{63}{7}[/tex]
- [tex]9[/tex]
Therefore, the answer to question #1 is 9.
Question 2:
1. Set up the equation to find the mean.
- [tex]\frac{28+20+30+25}{4}[/tex]
2. (Solving)
- [tex]\frac{28+20+30+25}{4}[/tex]
- [tex]\frac{103}{4}[/tex]
- [tex]25.75[/tex]
Therefore, the answer to question #2 is 25.75.
