First Problem
Problems 11.34 and 11.36. The data are in Table 11.18 in Hollander and Wolfe and also at http://www.stat.umn.edu/geyer/5601/hwdata/t11-18.txt
Second Problem
For the data in Table 6.4 in Hollander and Wolfe (H & W) also at http://www.stat.umn.edu/geyer/5601/hwdata/t6-4.txt
- Do a Kruskal-Wallis test of the hypotheses described in Problem 6.8 in Hollander and Wolfe. Describe the result of the test in terms of "statistical significance".
- Also do a conventional ANOVA on the same data.
Third Problem
For the data in Table 6.7 in Hollander and Wolfe (H & W) also at http://www.stat.umn.edu/geyer/5601/hwdata/t6-7.txt
- Do a Jonckheere-Terpstra test of the hypotheses described in Problem 6.19 in Hollander and Wolfe. Describe the result of the test in terms of "statistical significance".
- Also do a conventional normal theory test of the same hypotheses on the same data.
Fourth Problem
For the data in Table 7.2 in Hollander and Wolfe (H & W) also at http://www.stat.umn.edu/geyer/5601/hwdata/t7-2.txt
- Do a Friedman test of the hypotheses described in Problem 7.1 in Hollander and Wolfe. Describe the result of the test in terms of "statistical significance".
- Also do a conventional ANOVA on the same data.
Fifth Problem
For the data in Table 8.3 in Hollander and Wolfe (H & W) also at http://www.stat.umn.edu/geyer/5601/hwdata/t8-3.txt
- Do a test using Kendall's tau as the test statistic of the hypotheses described in Problem 8.1 in Hollander and Wolfe. Describe the result of the test in terms of "statistical significance".
- Also find the associated point estimate and an approximate 95% confidence interval.
- Also do the competing normal-theory parametric procedures on the same data.
(The problem just above is Problems 8.1, 8.20, and, except for a change of confidence level, 8.27 in H & W and more.)
