AP Statistics Review Confidence Intervals
... A Confidence Interval is an interval that is computed from sample data and provides a range of plausible values for a population parameter. A Confidence Level is a number that provides information on how much “confidence” we have in the method used to construct a confidence interval estimate. This l ...

Possible sources of bias include, for example, failing to calibrate the instrument or contaminating the samples by collecting them in bottles that were not properly cleaned. Errors such as these are called determinate and ...

... To determine whether smoking during pregnancy leads to lower birth weight of babies, we would compare a random sample of weights of new-born babies whose mothers smoke, with a random sample of weights of newborn babies of non-smoking mothers. By analysing the sample data, we would hope to be able to ...
