Confidence+Intervals

=Confidence Interval - Simulation= The concept of concept intervals is demonstrated by looking at the 95% confidence intervals for 100 sample means from a given population.

SAT Scores Simulation data is generated by a random digit generator N(1260, 209). There are 45 students in each sample and sigma is known. //Note that this model assumes the data is normally distributed and does not deal with scores that fall below 600 or above 2400.// Posted July, 2015

Confidence Interval Simulation - Student Height Height data for 200 students originates in a case table and is moved to a sampler engine. There are 35 students in each sample and sigma is known. Posted July, 2016.

500 Numbers Simulation data originates in a sampler engine. The sample size used is 40 numbers and sigma is known. Posted July, 2012; updated July 2013
