Document Summary
Chapter 14, pp 335-344 not including the reasoning of tests of significance. Statistical inference provides methods for drawing conclusions about a population from sample data. The reasoning of statistical estimation: 95% confidence interval 2 standard deviations in 95% intervals z* is usually 2. In practice, we don"t take many srss to estimate . Because the method has a 95% success rate, all. This we need is one srs of 217 eight-year-old american boys to compute just one interval interval of numbers between the values interval for . Note that the confidence level does not represent the probability that a specific interval computed from a sample contains the parameter. It has to do with the behavior of the cis in repeated samples. Whether or not one ci captures the parameter is unpredictable (and in practice, we"ll never know if it did or not because we don"t know the value of the parameter).
