I am a dean's list mathematics major and I couldn't follow this text at all. This is true because the book is poorly written in a very bland voice, the few examples are often difficult with little or nothing to do with common problems you will encounter, and as a whole, this book seems to assume that all of its readers have a solid background in statistics; the problem with that is this is used in introductory courses. Everything I learned in the class for which this text was required was from lectures, and I normally learn extremely well from text books. If you take a course that requires this text, either try to find another book or run (don't walk) to the good old drop and add department!
