<image>(2008 • Chaoyang District Mock Exam) To help students learn more about the Olympic Games, a middle school held an "Olympic Knowledge Competition." To understand the results of this competition, a portion of the students' scores (scores are integers, with a maximum of 100 points) was sampled and a histogram was drawn. Please answer the following questions based on this histogram:
(1) How many students' scores were sampled?
(2) In what range does the median of this sample data fall?
(3) If students who scored above 80 points (excluding 80 points) in this competition are eligible for awards, please estimate what percentage of the total participants can win awards?
