Please Answer ASAP. Thanks!
A simple random sample of size n is drawn from a population that is normally distributed. The sample mean,x, is found to be 105, and the sample standard deviation, s, is found to be 12.
(a) Construct a 96% confidence interval about if the sample size, n, is 22.
(b) Construct a 96% confidence interval about if the sample size, n, is 13.
(c) Construct a 95% confidence interval about if the sample size, n, is 22.
(d) Should the confidence intervals in parts (a)-(c) have been computed if the population had not been normally distributed?
