Statistics 3 builds on topics in the two earlier books in this strand. The work on random variables is extended, both from discrete to continuous variables, and also to include linear combinations of random variables. The rest of this book is devoted to inference: sampling methods; confidence intervals; the t test; the Wilcoxon signed rank test and the test for goodness of fit. Taken together with the two earlier books, this book is ideal for any statistics course at this level.
