A simple random sample of size n in drawn from a population that is normally distributed. The sample mean, X, is found to be 112, and the sample standard deviation, is found to be 10. (a) Construct a 95% confidence interval about if the sample siren, is 24 (b) Construct a 95% confidence interval about if the sample stre, n, is 14. (c) Construct a 90% confidence interval about if the sample size, n, is 24 (d) Could we have computed the confidence intervals in parts (a)-(e) i the population had not been normally distributed?
