6.119 Coverage percent of 95% confidence interval.

For this exercise, use the Confidence Interval applet. Set the confidence level at 95%, and click the “Sample” button 10 times to simulate 10 confidence intervals. Record the percent hit (that is, percent of intervals including the population mean). Simulate another 10 intervals by clicking another 10 times (do not click the “Reset” button). Record the percent hit for your 20 intervals. Repeat the process of simulating 10 additional intervals and recording the results until you have a total of 200 intervals. Plot your results and write a summary of what you have found.
