Carry out the simulation at each sample size to get the SD and use the 2SD method to approximate the margin of error with each of these three sample sizes. Then produce the 95% confidence interval for each of these three sample sizes. Round your answers to 3 decimal places, e. g. 0.752 For a sample size of 350, the standard deviation is and the confidence interval is .+-.
For a sample size of 1000, the standard deviation is and the confidence interval is plusminus.
For a sample size of 4500, the standard deviation is and the confidence interval is plusminus .
