A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 106, and the sample standard deviation, s, is found to be 10. (a) Construct a 98% confidence interval about u if the sample size, n, is 26. (b) Construct a 98% confidence interval about u if the sample size, n, is 17. (c) Construct an 80% confidence interval about u if the sample size, n, is 26. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed? (a) Construct a 98% confidence interval about u if the sample size, n, is 26.
