While attending the annual watermelon-seed-spitting contest in Hoosierville, Indiana, you notice that some kids seem to be better than adults at long-distance spitting.

At a week-long family reunion one year you notice that all the men in the family sit down and eat breakfast every day while the women in the family often skip breakfast preferring to have just a cup of coffee or tea. You wonder whether this is something about your family or whether this is a gender difference that tends to hold for larger populations. To test your hypothesis, you poll 200 people and ask whether they eat breakfast. Each individual gives one of three answers: YES, NO or SOMETIMES. The following is the data you obtained:
YES NO SOMETIMES
MALE 90 30 10
FEMALE 40 20 10

You are a researcher for an upstart health insurance company that wishes to set the rate of health insurance for their customers. The company has given you an assessment that allows you to determine a "health score" for each individual assuming that the health score will predict how long a person will live. You are skeptical about the use of the health score and first set out to determine whether the health score for a given individual actually predicts their longevity. You have therefore collected health scores from a set of individuals and matched it with their age when they died. A portion of the data is the table below (of course the full data set contains thousands of individuals!). Please analyze the data and report your results.

You are a researcher with the No-Blow Beans Company that is working to genetically modify beans in the hope that they will produce a variety that does not cause gas (i.e. flatulence). They have produced three varieties of beans and have asked you to begin testing them. Each week you have asked volunteers to consume 1 of the cans of beans (randomly selected), and you then record flatulent events for a period of 24 hours thereafter (never mind how). The process is repeated until each volunteer has consumed one can of each bean variety. Data are reported below. Please analyze the data and report your results.
- It turns out that you've made a horrible error in analyzing your data in (1) above. You forgot to check that the data were normally distributed. It turns out that the data are NOT normally distributed and you have to run your analysis all over again! Please re-run the analyses using the appropriate method and. report your results.
