... Solution: Let W and Z be independent N (0, 1) random variables. Let Xn = W for all n and Yn = Z for all n. Let X = W and Y = −W . It is easy to see that X and Y are both N (0, 1), and it is clear that Xn → X in distribution and Yn → Y in distribution. But X + Y = 0 whereas Xn + Yn is distributed as ...

Descriptive Statistics
... Populations of objects and individuals show variation with respect to various traits (e.g. height, political preferences, the working life of a light bulb, investment risk). It is impractical (or impossible) to observe all the members of the population. In order to describe the distribution of a tra ...

... What do we know about the errors ∆xi of direct measurements? First, the manufacturer of the measuring instrument must supply us with an upper bound ∆i on the measurement error. If no such upper bound is supplied, this means that no accuracy is guaranteed, and the corresponding “measuring instrument” ...

... I can determine the minimum sample size required when estimating a population proportion. I can interpret the level of significance. I can determine is a test is one-tailed or two tailed and if it is right or left tailed. I can find and interpret the p-value. I can make and interpret a decision base ...
