Z-Interval for the Mean - ClassCalc 

In this video, I show how to create a z-interval for the mean using ClassCalc. I do show all of the process steps and work that goes into the confidence interval in case you have to show all of the work. If you just need to find the answer to the confidence interval and margin of error using ClassCalc fast forward to about 8 minutes into the video. I know most teachers/professors require that the work be shown, so I cover all of the work shown including how to find the critical values.
