Document Summary

Interval (cid:224) we don"t know whether the 95% confidence interval from a particular sample is one of the 95% that capture u or one of the unlucky 5% that miss (cid:224) to say we are 95% confident that the unknown u (population mean) lies between 26. 2 and 27. 4 is basically saying we got these numbers using a method that gives correct results 95% of the time. : confidence intervals for a population mean. X + z: state what is the practical question hat requires estimating a parameter, plan identify the parameter, choose a level of confidence, and select the type of confidence interval that fits situation, solve carry out the work to calculate confidence interval, conclude once you have solved the math state the interval of your confidence values, the reasoning of tests of significance. A result with p = 003 is significant at the = 0. 05 level but not significant at = 0. 01 level: tests for a population mean.
