In 2014, the statistical news website Five ThirtyEight conducted a series of online polls regarding people's views of acceptable behavior when flying. They found that, of the 858 respondents who had flown at least once in their lifetime, 41% thought it was either "very" or
"somewhat" rude to recline your seat during a flight. A statistics instructor was curious if this result would differ for students at her school who had flown at least once. She took a simple random sample of 400 students from her school and collected data from the 327 who had flown at least once before. Of those 327 students, 56% thought it was either "very" or
"somewhat" rude to recline your seat. Part A: What is the population in the statistics instructor's study?
