A recent study asked U. S. adults to name 10 historic events that occurred during their lifetime that have had the greatest impact on the country. The most frequently chosen answer was the September 11, 2001, terrorist attacks, which was included by 77% of the 2,000 randomly selected U. S. adults. Construct and interpret a 99% confidence interval for the proportion of all U. S. adults who would include the 9/11 attacks on their list of 10 historic events.

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
