![### Study on Energy Expenditure in Rhesus Monkeys
Animals and people that take in more energy than they expend will get fatter. Here are data on 12 rhesus monkeys: 6 lean monkeys (4% to 9% body fat) and 6 obese monkeys (13% to 14% body fat). The data report the energy expended in 24 hours (kilojoules per minute) and the lean body mass (kilograms, leaving out fat) for each monkey.
#### Data Table
| | Lean | | Obese | |
|---|------------|---------|-------------|--------|
| | **Body Mass** | **Energy** | **Body Mass** | **Energy** |
| 1 | 6.4 | 1.23 | 7.9 | 0.97 |
| 2 | 8 | 1.2 | 9 | 1.43 |
| 3 | 8.9 | 1.46 | 10.1 | 1.16 |
| 4 | 9.5 | 1.71 | 12.7 | 1.43 |
| 5 | 10 | 1.03 | 11.5 | 1.25 |
| 6 | 9.2 | 1.23 | 11 | 1.3 |
### Questions for Analysis
1. **(a) What is the mean lean body mass of the lean monkeys?**
**Answer:**
\[
\bar{x} = \_ \_ \_ \_ \_ \ \text{kilograms.}
\]
2. **(b) What is the mean lean body mass of the obese monkeys?**
**Answer:**
\[
\bar{x} = \_ \_ \_ \_ \_ \ \text{kilograms.}
\]
### Notes
To find the mean body mass for the lean and obese monkeys, sum the body masses in each group and divide by the number of monkeys in that group.
**Lean Monkeys (Body Masses):**
