A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 107, and the sample standard deviation, s, is found to be 10. (a) Construct a 90% confidence interval about if the sample size, n, is 17. (b) Construct a 90% confidence interval about if the sample size, n, is 27. (c) Construct a 99% confidence interval about if the sample size, n, is 17. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?

Lower bound: 107.0: Upper bound: 107.1 (Use ascending order. Round to one decimal place as needed.)
