Notes on Sampling Distribution Models
... that were near 49% but varied above or below that by no more than 3.16% (1.58 x 2). The proportions supporting Kerry found in the two polls above 49% and 45.9% are both consistent with a true proportion of 49%. This is what we mean by sampling error. It is not really an error at all, but just variab ...

... 1. Give the mean and standard deviation for the sampling distribution of pˆ1 pˆ 2 . 2. What conditions must be met to say the sampling distribution is normal and to use the above formula fo the standard deviation? 3. Give the formula for the standard error when calculating a confidence interval fo ...
