CHAPTER 8: CONFIDENCE INTERVALS FOR ONE POPULATION MEAN 8.1: Estimating a population mean • Common problem in statistics is to obtain information about the mean, ������������, of a population. • If population is small, we can ordinarily determine ������������ exactly by first taking a census and then computing ������������ from the population data. • If population is large, often in practice, taking census is generally impractical, extremely expensive, or impossible. Nonetheless, we can usually obtain sufficiently accura te information about ������������ by taking a sample from the population. Recall • A parameter is a characteristic of the population • A statistic is a characteristic of the sample Ex: • The population mean and population standar
