Unformatted text preview: Chapter 8: Estimation of the Mean and Proportion Bin Wang [email protected] Department of Mathematics and Statistics University of South Alabama Mann E6 1/23 8.1 Estimation: An Introduction Definition (Estimation) Estimation is a procedure that we assign a value to a population parameter based on a corresponding sample statistic. Mann E6 2/23 8.1 Estimation: An Introduction Definition (Estimation) Estimation is a procedure that we assign a value to a population parameter based on a corresponding sample statistic. Definition (Estimator and Estimate) Estimate refers to the value(s) assigned to a population parameter based on a corresponding sample statistic. Estimator is the sample statistic used to estimate the population parameter. Mann E6 2/23 8.2 Point and Interval Estimates Definition (Point Estimate) The value of a sample statistic used to estimate a population parameter. Mann E6 3/23 8.2 Point and Interval Estimates Definition (Point Estimate) The value of a sample statistic used to estimate a population parameter. Definition (Point Estimation) The procedure use a point estimate to estimate a population parameter. Mann E6 3/23 8.2 Point and Interval Estimates Definition (Interval Estimation) Interval estimation is a procedure that we construct an interval around the point estimate and state that this interval is likely to contain the corresponding population parameter. An interval is consisted of lower limit and upper limit . Mann E6 4/23 8.2 Point and Interval Estimates Definition (Interval Estimation) Interval estimation is a procedure that we construct an interval around the point estimate and state that this interval is likely to contain the corresponding population parameter. An interval is consisted of...
