A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 105, and the sample standard deviation, s, is found to be 10. (a) Construct a 95% confidence interval about p if the sample size, n, is 13. (b) Construct a 95% confidence interval about p if the sample size, n, is 28. (c) Construct a 98% confidence interval about p if the sample size, n, is 13. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed
