A 99% confidence interval for the mean population height of male college freshman is calculated from a random sample of 50, and the confidence interval is (64,74) inches. Select all answers that apply. 2 For the instructor, this was question 28. Choose all that apply. Interpretation: 99% of the time the population mean lies between 64 inches to 74 inches Interpretation: 99% of the confidence intervals will contain the population mean. The population mean is random. The confidence interval is random. A 90% confidence interval will be shorter in length. A 90% confidence interval will be longer in length.
