Homework: 9.2 MyL... Question 5, 9.2.1/ HW Score: 50%, 4 of 8 points Part 1 of 6 O Points: 0 of 1 Save A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 109, and the sample standard deviation, s, is found to be 10. (a) Construct a 95% confidence interval about u if the sample size, n, is 16. (b) Construct a 95% confidence interval about u if the sample size, n, is 20, (c) Construct a 99% confidence interval about u if the sample size, n, is 16. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
