est: Unit 6 TEST-9.1 & 9.2 Question 7 of 10 A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 101, and the sample standard deviation, s, is found to be 9. (a) Construct a 90% confidence interval about (b) Construct a 90% confidence interval about (c) Construct a 98% confidence interval about if the sample size, n, is 22. if the sample size, n, is 15. if the sample size, n, is 22. (d) Should the confidence intervals in parts (a)(c) have been computed if the population had not been normally distributed? (a) Construct a 99% confidence interval about if the sample size, n, is 22. Lower bound: Upper bound: (Round to one decimal place as needed.) (b) Construct a 99% confidence interval about if the sample size, n, is 15. Lower bound Upper bound (Round to one decimal place as needed.) How does decreasing the sample size affect the margin of error. E? OA. As the sample size decreases the margin of error decreases OB. As the sample size decreases, the margin of error increases C. As the sample size decreases the margin of error stays the same (c) Construct a 96% confidence interval about if the sample size. n. is 22 Lower bound: Upper bound (Round to one decimal place as needed.) Compare the results to those obtained in part (A) How does decreasing the level of confidence affect the size of the margin of error. E OA. As the level of confidence decreases the size of the interval increases OB. As the level of confidence decreases the size of the interval stays the same OC.
