Section 2 · Lecture 08 · Normal Distribution

Normal Table Reader

Normal tables are printed only for the standard Normal, Z ~ N(0, 1), and only for positive values. So every question is solved the same way: standardise, rewrite it into the form the table gives, and look it up. To work backwards from a percentage, follow the same steps in reverse.
