8Statistical Intervals for a Single Sample
... lies in the realization that a CI is a random interval because in the probability statement defining the end-points of the interval (Equation 8-4), L and U are random variables. Consequently, the correct interpretation of a 100(1 )% CI depends on the relative frequency view of probability. Specif ...

Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process, and each subset of k individuals has the same probability of being chosen for the sample as any other sub ...

So we will consider our r to be significant if it lies beyond 95% of the t-distribution on either side. In short, this ...

... (b) We see in dotplot A that quite a few of the sample proportions (when n = 20) are less than 0.25 or greater than 0.45, so being off by more than 0.10 would not be too surprising. While it is possible to be that far away in dotplot B (when n = 100), such points are much more rare, so it would be so ...
