**Topic:** Calculating the Margin of Error for a 95% Confidence Interval **Objective:** To understand how to calculate the margin of error for a 95% confidence interval when estimating the population mean, and explore the impact of sample size on the margin of error. --- **Problem Statement:** Find the margin of error for a 95% confidence interval for estimating the population mean when the sample standard deviation equals 90. Consider two sample sizes: (i) 400 and (ii) 1600. What is the effect of the sample size? --- **Solution:** (i) **Calculation for Sample Size of 400:** Calculate the margin of error for a 95% confidence interval when the sample size is 400 and the sample standard deviation is 90. - **Result:** 1.966 (Rounded to two decimal places as needed.) --- *Note:* To complete the analysis, solve for the case where the sample size is 1600 and determine how the margin of error changes with increasing sample size.
