Confidence Intervals for Population Means

Confidence Intervals for Population Means. BUSA 2100, Sections 8.1, 8.2. Estimation Process. Point estimates are single numbers, e.g. X-bar = $35,000. Point estimates should be close to the true population mean (or proportion), but are almost never exactly equal.
