This tutorial explains how to use the following functions on a TI-84 calculator to find normal distribution probabilities. To find the z-score for a data set you can use ti-84 plus to find the mean and standard deviation and then use the z-score equation or use the TI-84 Plus invNorm function with percentiths as an argument. For example if the mean is 100 with a stan.

You can use the invNorm function on a TI-84 calculator to find z critical values associated with the normal distribution. InvNormprobability where. Step 3 In the last two parts students are to find the corresponding x-value given a percentile and then given a z-score and they are asked to find the corresponding percentile and x-value.

population standard deviation. The Z-score is identical to the number of standard deviations from the mean so use the appropriate 2nd Distr menu item press to see the syntax then put in the numbers and do your calculation.
