Invite you to refer. | 9 Inferences Based on Two Samples Confidence Intervals and Tests of Hypotheses CONTENTS Identifying the Target Parameter Comparing Two Population Means Independent Sampling Comparing Two Population Means Paired Difference Experiments Comparing Two Population Proportions Independent Sampling Determining the Sample Size Comparing Two Population Variances Independent Sampling Optional Where We ve Been Explored two methods for making statistical inferences confidence intervals and tests of hypotheses Studied confidence intervals and tests for a single population mean m a single population proportion p and a single population variance s2 Learned how to select the sample size necessary to estimate a population parameter with a specified margin of error Where We re Going Learn how to identify the target parameter for comparing two populations Learn how to compare two means by using confidence intervals and tests of hypotheses Apply these inferential methods to problems in which we want to compare two population proportions or two population variances Determine the sizes of the samples necessary to estimate the difference between two population parameters with a specified margin of error 462 CHAPTER 9 Inferences Based on Two Samples Statistics IN Action ZixIt Corp. v. Visa USA Inc. A Libel Case The National Law Journal Aug. 26-Sept. 2 2002 reported on an interesting court case in volving ZixIt Corp. a start-up Internet credit card clearing center. ZixIt claimed that its new online credit card processing system would allow Internet shoppers to make purchases without revealing their credit card numbers. This claim violated the established protocols of most major credit card companies including Visa. Without the company s knowledge a Visa vice president for technology research and development began writing e-mails and Web site postings on a Yahoo message board for ZixIt investors .
