A poll found that a particular group of people read an average of 15.2 books per year. The pollsters are 99% confident that the result from this poll is off by fewer than1.85 books from the actual average x. Express this situation as an inequality involving absolute value, and solve the inequality for x to determine the interval in which the average is likely to fall. Express the situation as an inequality involving absolute value
