A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, Is found to be 114 and the sample standard deviation, s, is found to be 10 (a) Construct a 90% confidence interval about if the sample size, n, is 24 (b) Construct a 90% confidence interval about if the sample size, n, is 18 (c) Construct an 80% confidence interval about if the sample size, n, is 24. (d) Could we have computed the confidence intervals in parts (a)-(e) if the population had not been normally distributed? Click the icon to view the table of areas under the t-distribution n P (a) Construct a 90% confidence interval about us if the sample size, n, is 24 Lower bound: Upper bound I (Use ascending order. Round to one decimal place as needed.)
