Rossman/Chance applets for this interpretation. The applet is located at: http;//www.rossmanchance.com/applets/ConfSim.html. We will be performing two simulations, one with z with sigma and one with a t distribution. The input information is at the left hand of the screen. Both simulations will use a mu of 5, a sigma of 2 (I know that it is supposed to be s for the t distribution), and use a sample size of 100. Please use a confidence level (Conf level) of 95%. To run the simulation, press .To reset the simulation, press. You will be reporting the items between the last grey line and the Sort: The Intervals containing mu which is for the number of intervals listed and the Running Total. Conf level 95% Intervals containing mu 288/300 = 96.0% Running Total 288/300 = 96.0 % Just to the right of the input, you will see a figure of all of the confidence intervals generated. If they contain the true mean, the line will be in green If they don't contain the true mean, the line will be in red. Set the distribution to z with sigma and the Intervals to 30. Press Sample. Record both the Intervals containing mu and the Running total. Also copy the diagram showing the intervals into your lab report. Repeat pressing Sample and recording the percentages until you have completed 300 total intervals. You do not need to present the graphic except for the first time. After pressing Reset, repeat part 1, except use the t distribution instead. How are the graphs from parts 1 and 2 expected to be different? Did you notice that different in the graphs? Were any of the percentages exactly 95%? If some were, how many? Does this imply that there is a problem with the calculations done with the applet? Please explain your answer. Reset the simulation and choose the t distribution method with Intervals of 100. Press Sample until the Running Total is dose to 95% (within 0.2%) and report the final cumulative total.. You do not need to report the totals each time. What do you think 'mathematically large' is in this circumstance. Previous question
