This is because I’d deep ocean,tsunami waves may appear only a foot or so high.But as they approach the shoreline and enter shallower water they slow down and begin to grow in energy and height.Since the tops of the waves move faster than the bottoms so it causes them to rise faster.So...if a tsunami is in deep waters it does not really hit the shore and splash around to hurt anyone or anything or any people.It is fine because it’s in the middle of the ocean and not on the shoreline.I hoped I helped even a little bit :3

Answer: D) 4</h3>
===========================================================
Explanation:
The width of the confidence interval is 20-12 = 8 units. That cuts in half to get 8/2 = 4 which is the margin of error.
The center of the confidence interval is (12+20)/2 = 32/2 = 16. Add four onto this to get 16+4 = 20, which is the right endpoint. Subtract four from the center to get 16-4 = 12, which is the left endpoint.
Effectively, it's like saying "an archer aims for the value 16 on the number line, and the arrow could land as high as 20 or as low as 12".
