Question
**Exercise: Calculating Margin of Error** A sample of size \( n = 51 \) is drawn from a population whose standard deviation is \( \sigma = 47 \). **Part 1 of 2** (a) Find the margin of error for a 90% confidence interval for \( \mu \). Round the answer to at least three decimal places. The margin of error for a 90% confidence interval for \( \mu \) is \(\_\_\_\_\). **Part 2 of 2** (b) If the sample size were \( n = 72 \), would the margin of error be larger or smaller? \[ \text{(Choose one)} \], because the sample size is \[ \text{(Choose one)} \]. *[Submit Assignment]* button is shown at the bottom of the page. This exercise is designed to help students understand how the margin of error changes with different sample sizes and confidence levels.
