z-scores and Normal Distributions (M/Tu, Sept 24/25)

Here are the notes/handouts that cover the bulk of today's lesson:

• z-tables - PRINT THIS OUT! (z-tables are on page 1... ignore the tables on page 2 for now)
• Today's Class Notes: Normal Distributions

Here are the Powerpoint slides from the lesson, in case you wish to review them (however they do NOT have the work for the problems written out):

• Powerpoint [WEB] 3.1 - z-scores and the Normal Model

If you are still looking for additional reinforcement, we would recommend reading chapter 6 in the textbook for additional guidance.

Videos for Normal Distributions

The following videos which were put together by Mr. Ziebell are a great resource:

• First Day Normal Distribution
• The Empirical Rule (68-95-99.7 Rule)
• Using the z-score formula
