mple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 112, and the sample standard viation, s, is found to be 10. Construct a 96% confidence interval about u if the sample size, n, is 24. Construct a 96% confidence interval about μ if the sample size, n, is 18. Construct a 95% confidence interval about u if the sample size, n, is 24.

ents ccess Library Options ns bols ly cloudy A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 112, and the sample standard deviation, s, is found to be 10. (a) Construct a 96% confidence interval about u if the sample size, n, is 24. (b) Construct a 96% confidence interval about µ if the sample size, n, is 18. (c) Construct a 95% confidence interval about u if the sample size, n, is 24. (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 96% confidence interval about u if the sample size, n, is 24. Lower bound: 107.6: Upper bound: 116.4 (Use ascending order. Round to one decimal place as needed.)
