Estimating the Value of a Parameter Using Confidence Intervals Chapter 9 Estimating the Value of a Parameter Using Confidence Intervals

Overview We apply the results about the sample mean to the problem of estimation Estimation is the process of using sample data to estimate the value of a population parameter We will quantify the accuracy of our estimation process

Chapter 9 Sections Sections in Chapter 9 The Logic in Constructing Confidence Intervals about a Population Mean where the Population Standard Deviation is Known Confidence Intervals about a Population Mean in Practice where the Population Standard Deviation is Unknown Confidence Intervals about a Population Proportion Putting It All Together: Which Procedure Do I Use? 9.2 9.3 9.1 9.4
