The 2011 Statistical Abstract of the United States includes a table reporting that a national survey in the fall of 2009 found that14.3% of American adults played a board game in the past year. We can use this sample result to estimate the proportion of all adult Americans who had played a board game in the past year.?

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 300, the standard deviation is i and the confidence interval is i i For a sample size of 1500, the standard deviation is i and the confidence interval is i + i For a sample size of 4000, the standard deviation is i and the confidence interval is i eTextbook and Media
