Find the margin of error for a 95% confidence interval for μ. Round the answer to at least three decimal places. The margin of error for a 95% confidence interval for μ is Part 2 of 2 (b) If the sample size were n-63, would the margin of error be larger or smaller? (Choose one) because the sample size is (Choose one) X smaller larger LUC Tod Find the critical value f/2 needed to construct a confidence interval of the given level with the given sample size. Round the answers to three decimal places. Part 1 of 4 (a) For level 90% and sample size 8 Critical value= Part 2 of 4 (b) For level 99% and sample size 11 Critical value= Part 3 of 4 (c) For level 95% and sample size 25 Critical value= M Question 2 of 4 (1 point) Attempt 1 of 1 View question in a popup 1h 15m Remaining A sample of size n-58 is drawn from a population whose standard deviation is o=42.
