According to a December 2020 Gallup Poll, nurses were rated as the most ethical and honest profession.  Eighty-nine percent (89%) of Americans rated nurses’ honesty and ethical standards as either “high” or “very high”.  (By comparison, the rating for car dealers was 8%.) Based on this information, in a randomly-selected group of 600 Americans, what is the probability that at least 550 would rate nurses high or very high for honesty and ethics?
