Objective 4: Construct and Interpret a Confidence Interval for a Population Mean 9.2 Estimating a Population Mean O of 1 Point 9.2.17 Question Help 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 an 80% confidence interval about p if the sample size, n, is 23. (b) Construct an 80% confidence interval about p if the sample size, n, is 27. (c) Construct a 90% confidence interval about u if the sample size, n, is 23. (d) Could we have computed the confidence intervals in parts (a)-(C) if the population had not been normally distributed?
