%: 9.2.21 Question Help V a Asimple random sample of size n is drawn. The sample mean, )_(, is found to be 18.3, and the sample standard deviation, 5, is found to be 4.1. 5 Click the icon to view the table of areas under the t-distribution. (3) Construct a 95% condence interval about p if the sample size, n, is 35. Lower bound: 16.89 ; Upper bound: 19.71 (Use ascending order. Round to two decimal places as needed.) (b) Construct a 95% condence interval about p if the sample size, n, is 61. Lower bound: 17.25 ; Upper bound: 19.35 (Use ascending order. Round to two decimal places as needed.) How does increasing the sample size affect the margin of error, E? A. The margin of error does not change. 3 B. The margin of error decreases. C. The margin of error increases. (c) Construct a 99% condence interval about p if the sample size, n, is 35. Lower bound: 20.19 ; Upper bound: 16.41 (Use ascending order. Round to two decimal places as needed.)
