Scores on a math achivement test are normally distributed with a mean of 150 and standard deviation of 30.

Whatis the score of a peron who scored lower than 97.5% of all scores?

( I think this is a reverse z-score, and if it is, I think i missed the class we learned that).

Due to the fact that sneezes & orgasms are similar actions, people who have dainty little cat-sneezes have smaller, less intense orgasms, and people with big loud, intense sneezes have big orgasms? Do you believe this? Anyone with medical training have any opinions?

Not sure what i am on about? let me explain.
whenever we switch on an electrical device, chances are it is earthed, as in any residual current is sent back into the planet one way or another. what i am asking is, how long will it be before we pump so much energy into the earth that something mad happens, will the earth turn into a huge magnet for example and attract unwanted lumps of space debris? or will something worse happen?
