Example:
Alma has developed a new kind of antibiotic. For the antibiotic to be sufficiently effective, it has to kill at least 90% of bacteria when applied to a harmful bacteria culture. She applied her antibiotic to a petri dish full of harmful bacteria, waited for it to take effect, and then tried to estimate the percentage of dead bacteria in it.
She took a random sample of 300 bacteria, and found that 94% of them were dead. Then, she calculated the margin of error and found that the true percentage of dead bacteria is most likely to be above 90%.
