2.4 Computing for Area Under The Curve - Normal Probability Distribution Using Ti84


This lesson will show how to use ti-84 in computing for the probability problem involving the standard Normal curve. In a Normal distribution wherein the mean, standard deviation and the sample size of the sampling distribution is given, finding the area under the curve can be found efficiently using a calculator. 01:02 1. P( x greater than 740 hours )

  • 04:15 2. P( x less than 700 hours )
  • 06:18 3. P( 715 x is in between 732 )
  • 08:18 4. P( within 5 hours of the population mean )
