As you increase the confidence level (everything else remaining the same), the width of the confidence interval increases.

AND

As you increase n(assuming everything else remains the same), the width of the confidence interval increases.

And how can all that concrete turn to powder, apparently before even hitting the earth,, where did all that energy come from to completely pulverize 110 steel reinforced concrete slabs, break hundreds of steel columns, AND allow the entire structure to come to rest in only 10 seconds ? A billiard ball would take 10 seconds to fall 110 stories.. How can an entire steel and concrete structure, not only collapse at freefall speed, but also become pulverized, and shreeded on the way down ? This problem bothers me alot. I want real answers please,, thank you..
