Length of a confidence interval. Which confidence interval would be shorter, and by how much: a confidence interval computed using a sample size of 150 or a confidence interval computed using a sample size of 1350 (or 9 times bigger)? Assume that the confidence level is 95% for both confidence intervals and that the only difference between them is the sample size. Explain your reasoning, including how much smaller, numerically, the margin of error will be.
