Assignment Instructions: for each scenario, tell me the type of test (one-sample z-test, one-sample t-test, independent samples t-test, paired t-test, confidence interval, one-way ANOVA, two-way ANOVA, or repeated measures ANOVA) and tell me why you think it is that particular test
1. Al thinks that adults who watch cartoons are more creative than those who do not. He thinks this is especially true for women more than men. He measures creativity in a random sample of 400 adults.
2. Bernard still doesn't believe Janet's pancakes make a difference in test scores, despite Janet's data. He asks Janet (who readily agrees) to make a very large batch of blueberry pancakes. Bernard then has 100 people taste test them and evaluate the pancakes on the Bernard Standardize Deliciousness Scale (µ = 5) where participants rate the pancakes on a 0-10 scale.
3. Franklin doesn't believe in ghosts but he knows many people do. He would love to know whether there are differences in degree of ghost belief between people who attend church and those who do not. He samples 500 people randomly on the internet.
4. Shauna is convinced that her fifth-grade students would behave themselves better if she threatened them with an accordion concert. She records number of detentions before and after wielding her accordion in their direction.
5. Fred always has theories about his students and who is more likely to pass his tests. He thinks that only children, oldest of multiple, and youngest of multiple children perform differently. He samples 70 children from his classes.
6. Ramiro has worked with his 3rd grade students on spelling all year (to the detriment of the rest of the curriculum). He is a first-year teacher and Mr. Wilks, the other 3rd grade teacher at this school, consistently talks smack about how his students always meet the population mean on the standardized Spelling Achievement Test, and that nobody else in the school's students ever do that. Ramiro is so confident that he bets Mr. Wilks that his students will perform significantly better than the population (µ = 100, σ = 15). On the day he gets his students' scores, they have an M = 142 (N = 30).
