To fill out the last column of the table (Deer Population Change), we need to use the following formula:

\[
\text{Deer Population Change} = \text{Deer Offspring} - (\text{Predation} + \text{Starvation})
\]

Now, let's apply this formula year by year:

### 2016:
\[
\text{Deer Population Change} = 920 - (480 + 240) = 920 - 720 = +200
\]

### 2017:
\[
\text{Deer Population Change} = 1000 - (640 + 500) = 1000 - 1140 = -140
\]

### 2018:
\[
\text{Deer Population Change} = 944 - (880 + 180) = 944 - 1060 = -116
\]

### 2019:
\[
\text{Deer Population Change} = 996 - (1120 + 26) = 996 - 1146 = -150
\]

Now, the table with the last column filled:

| Year  | Coyote Population | Deer Population | Deer Offspring | Predation | Starvation | Deer Population Change |
|-------|-------------------|-----------------|----------------|-----------|------------|------------------------|
| 2015  | 10                | 2000            | 800            | 400       | 100        | +300                   |
| 2016  | 12                | 2300            | 920            | 480       | 240        | +200                   |
| 2017  | 16                | 250             | 1000           | 640       | 500        | -140                   |
| 2018  | 22                | 2360            | 944            | 880       | 180        | -116                   |
| 2019  | 28                | 2224            | 996            | 1120      | 26         | -150                   |

Next, you will need to graph the Deer and Coyote populations from 2016 to 2019, as you did for 2015.

Do you have any questions or want more details?

Here are some relative questions to expand on the problem:
1. How does the change in Coyote population affect the Deer population?
2. What happens to the Deer population when predation and starvation rates increase?
3. Could the Deer population recover in the future if the coyote population decreases?
4. What might be the ecological consequences if the Deer population continues to decline?
5. How could an external factor (like habitat change) alter the trends in both populations?

Tip: When graphing data, use distinct colors or patterns to clearly represent different variables, like the Coyote and Deer populations.
