Part 1 of 6 O Points: 0 of 1 A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 106, and the sample standard deviation, s, is found to be 10. (a) Construct a 90% confidence interval about u if the sample size, n, is 18. (b) Construct a 90% confidence interval about u if the sample size, n, is 22. (c) Construct a 96% confidence interval about u if the sample size, n, is 18. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed? Click the icon to view the table of areas under the t-distribution. (a) Construct a 90% confidence interval about u if the sample size, n, is 18. Lower bound: : Upper bound: (Use ascending order. Round to one decimal place as needed.)
