Matched/Paired Samples: Are not Indep; Occur when two values are obtained on the same item at different times or locations, or when the sampling process selects pairs of items. (Such as before and after)
**Correction: When using propprtions, there are 2 formulas used for finding the error. One is for the hypothesis test and one is for confidence intervals. I used one formula for both on the worksheests and mock exam. Be sure to change the formula for the Confidence Intervals.
