Section 8.1 Confidence Intervals: The Basics
{"Image DocumentName": "Section 8.1 Confidence Intervals: The Basics", "Image ImageDescription": "Summary. In this section, we learned that\u2026 To estimate an unknown population parameter, start with a statistic that provides a reasonable guess. The chosen statistic is a point estimator for the parameter. The specific value of the point estimator that we use gives a point estimate for the parameter. A confidence interval uses sample data to estimate an unknown population parameter with an indication of how precise the estimate is and of how confident we are that the result is correct. Any confidence interval has two parts: an interval computed from the data and a confidence level C. The interval has the form. estimate \u00b1 margin of error. When calculating a confidence interval, it is common to use the form. statistic \u00b1 (critical value) \u00b7 (standard deviation of statistic)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
