A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 110, 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 19 (b) Construct a 95% confidence interval about u if the sample size, n, is 27. (c) Construct a 96% confidence interval about u if the sample size, n, is 19 (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?

(a) Construct a 95% confidence interval about u if the sample size, n, is 19 Lower bound: 105.2 ; Upper bound: 114.8 (Use ascending order. Round to one decimal place as needed.) (b) Construct a 95% confidence interval about u if the sample size. n, is 27 Lower bound: : Upper bound: (Use ascending order. Round to one decimal place as needed.)
