(a) Construct a 95% confidence interval about if the sample size, n, is 12 Lower bound 102 6 Upper bound 115.4 (Use ascending order. Round to one decimal place as needed) (b) Construct a 95% confidence interval about if the sample size, n, is 27 Lower bound: 105.0 Upper bound: 113.0 (Use ascending order. Round to one decimal place as needed.) How does increasing the sample size affect the margin of error, E? As the sample size increases the margin of error stays the same X As the sample size increases, the margin of error increases *As the sample size increases the margin of error decreases (c) Construct a 98% confidence interval about if the sample size n. 12 Lower bound: 101 2Upper bound 1168 (Use ascending order Round to one decimal place as needed
