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

1. 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".
2. 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

1. 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".
2. 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

1. 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".
2. 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

1. 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".
2. Also find the associated point estimate and an approximate 95% confidence interval.
3. 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.)
