Sample size problems: Just state the minimum sample size Confidence intervals: state your result is a sentence, like "we are 95% confident that ? Is between blank and blank " Hypothesis tests: perform the appropriate hypothesis test, including all 5 steps. 1. Ho & H1 2. a= 3. Test 4. Test statistic and p-value 5. Decision about H0/ conclusion about H1 If the necessary conditions are not let, use the appropriate alternative test. 1. One Proportion- Binomial 2. Two proportion- randomization test for two proportions 3. One mean - sign test 4. Paired difference- Wilcoxon Signed Ranks 5. Two mean test- Mann Whitney 6. Anova- Kruskal Wallis 18) Ten COS Math 21 students were asked how many hours they studied for their final. Here are their responses. 8 10 12 7 9 13 8 10 14 10 Twelve COS math 200 students were asked the same questions. Here are their responses. 6 7 5 8 10 6 8 5 0 11 9 6 At the 0.05 level of significance, test the claim that the mean number of hours studied by Math 21 students is greater than the mean number of hours studied by math 200 students
