I am kind of disturbed that so many students are having problems with introductory statistics and must resort to asking for here in this newsgroup. As a former stat student, I must confess that I had my share of uncaring stat professors that truly didn't care whether I learn anything or not. I think there's a lot to say about the industry if a professor cannot even explain how to look up the normal probability table. I know kids are lazy these days but I am positive that most of them can learn to read the table if the steps are clearly explained once or twice. To the original poster, are you the only one in the class that can't do this or the majority of the students are struggling with this? . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
