A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x-bar, is found to be 110, and the sample standard deviation, s, is found to be 10. (a) Construct a 96% confidence interval about μ if the sample size, n, is 17.
(b) Construct a 96% confidence interval about μ if the sample size, n, is 28.
(c) Construct a 98% confidence interval about μ if the sample size, n, is 17.
(d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
