You want to test the hypothesis that the average NYU student spends no more than $600 on subway fares per academic year. You happen to know that variance in subway fare spending is $900. You plan to test this hypothesis by asking n students to track their subway expenses over the course of the academic. If you have a significance level of .01, how many students would you have to track to have a 90% chance of rejecting the null hypothesis when the average subway spending is actually $620. (It is a one-sided hypothesis test with H0: µ = $600 and H1: µ > $600)

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
