A simple random sample of size is drawn from a population that is normally distributed. The sample mean, X. is found to be 105, and the sample standard dedin, is found to be 10 (a) Construct 95% confidence interval about the sample size is 19 (b) Construct a 95% confidence interval about the sample size, n, is 26 (c) Construct a 96% confidence interval about if the sample size is 19 (d) Could we have computed the confidence intervals in parts (HC) if the population had not been normally distributed?
