sampling distribution model
... We would expect the histogram of the sample proportions to center at the true proportion, p, in the population. As far as the shape of the histogram goes, we can simulate a bunch of random samples that we didn’t really draw. It turns out that the histogram is unimodal, symmetric, and centered at p. ...

... 24. In the situation described in Question 22, it is desired to make the answer obtained using the normal approximation closer to the exact answer. Which of the following would make the normal approximation more accurate? (a) allowing in some way for the fact that the number of sampled males has to ...

... The Central Limit Theorem is a statement about the characteristics of the sampling distribution of means of random samples from a given population. That is, it describes the characteristics of the distribution of values we would obtain if we were able to draw an infinite number of random samples of ...
