(b) Construct a 95% confidence interval about μ if the sample size, n, is 61. Lower bound: Upper bound: (Use ascending order. Round to two decimal places as needed.) How does increasing the sample size affect the margin of error, E? O A. The margin of error does not change. O B. The margin of error decreases. OC. The margin of error increases. (c) Construct a 99% confidence interval about µ if the sample size, n, is 34.
