Transcribed Image Text:A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 108, and the sample standard deviation, s, is found to be
10.
(a) Construct a 90% confidence interval about µ if the sample size, n, is 28.
(b) Construct a 90% confidence interval about u if the sample size, n, is 11.
(c) Construct an 80% confidence interval about u if the sample size, n, is 28.
(d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
