Let's analyze each statement one by one based on the given table.

1. There were more boys surveyed than girls.
- Number of boys surveyed: 118
- Number of girls surveyed: 113
- Since 118 > 113, this statement is true.

2. More boys chose skiing as their favorite outdoor activity than girls.
- Boys who chose skiing: 25
- Girls who chose skiing: 20
- Since 25 > 20, this statement is true.

3. Twice as many students chose canoeing as their favorite outdoor activity than those who chose fishing.
- Total students who chose canoeing: 35 (13 boys + 22 girls)
- Total students who chose fishing: 70 (36 boys + 34 girls)
- For this statement to be true, 35 should be twice the number of 70.
- 35 is not equal to 2 * 70 (which is 140), so this statement is false.

4. More girls chose camping as their favorite outdoor activity than boys.
- Girls who chose camping: 37
- Boys who chose camping: 44
- Since 37 < 44, this statement is false.

5. More students chose camping as their favorite outdoor activity than the combined number of students who chose canoeing or skiing.
- Total camping: 81 (44 boys + 37 girls)
- Total canoeing and skiing combined: 35 + 45 = 80
- Since 81 > 80, this statement is true.

6. More girls chose canoeing as their favorite outdoor activity than those who chose skiing.
- Girls who chose canoeing: 22
- Girls who chose skiing: 20
- Since 22 > 20, this statement is true.

Based on the analysis, the correct statements are:
- There were more boys surveyed than girls.
- More boys chose skiing as their favorite outdoor activity than girls.
- More students chose camping as their favorite outdoor activity than the combined number of students who chose canoeing or skiing.
- More girls chose canoeing as their favorite outdoor activity than those who chose skiing.

So the correct answers are:
- There were more boys surveyed than girls.
- More boys chose skiing as their favorite outdoor activity than girls.
- More students chose camping as their favorite outdoor activity than the combined number of students who chose canoeing or skiing.
- More girls chose canoeing as their favorite outdoor activity than those who chose skiing.
