Researchers want to examine the effect of scent on memory. A total of 9 people were recruited for the study. Each person randomly assigned to one of the three experimental groups. Each person was asked to read a passage from a book. A week later, each study participant was asked to recall as much information as they could from the previously read passage.  Researchers determined a score for each subject representing the facts that have been correctly recalled. The data are...

To understand the implications of expanding health coverage, researchers want to know if people with health insurance use more health care than do people without it. To test this, they leveraged an administrative lottery that randomly assigned individuals to either receive public health care or not. Using the data below on the number of medical interactions (e.g., hospital visits or doctor appointments), test whether individuals with health insurance use health services differently than do those without it (alpha=0.1, two tails).No...
