Answer:
Step-by-step explanation:
There are two answers to this. 
1. 
The order is ACB. That means that B is beyond C.
In which case AB = AC + BC
AB = 22 + 13
AB = 35
2
The order is ABC (which means that B is between A and C.
AB = AC - BC
AB = 22 - 13
AB = 9
Please don't ask me what the answer is. The question does not make it  clear enough to give you one answer. I do suggest you draw a diagram to show both possibilities. Your teacher will likely applaud you for poking holes in the question.

Answer:
Option A) 
Confidence interval decreases
Step-by-step explanation:
If we increase the sample size, then,
- The standard error of the interval decrease.
- If the standard error increase, the margin of error of the interval decrease.
- If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.
Thus, the correct answer is 
Option A) 
Confidence interval decreases
