We need to simulate what a distribution should look like if the population value is the same as the null hypothesis. Then ...

II. Finite Sample Properties of Estimators
... More generally, an estimator W of a parameter θ can be expressed as an abstract mathematical formula as below: W = h(X1 , X2 , ..., Xn ), for some known function h of the random variables X1 , X2 , ..., Xn . W , of course, is a random variable, and the value of W changes depending on the sample you ...

Linear regression
... The slope b1 is the change in Y associated with a unit change in X. The intercept is the value of the population regression line when X = 0; it is the point at which the population regression line intersects the Y axis. In some econometric applications, such as the application in Section 4.7, the in ...

... (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 ...
