Using the TI - Normalcdf

In class we began working with the TI-83/84 to find percentages under the Normal curve. Check out this document if you forgot how to use the Normalcdf( function on your TI calculator.

"After reviewing the play, the ruling on the field has been overturned." Please mentally substitute the word "interval" when ever I say "range." Range has a specific meaning in statistics and therefore my use in this clip is not correct, range is a number not an interval. Other than that this is the best video ever recorded in the history of the world, or at least should be pretty useful if you forgot how to use the calculator to find the area under a normal curve for a specified interval.
