A researcher is interested in examining whether the location that a person lives is related to the number of hours that they spend on the internet each week. The researcher collected data from a sample of 30 participants who were classified in one of three groups: (1) 10 people who live in an urban setting, (2) 10 people who live in a suburban setting, and (3) 10 people who live in a rural setting. Each participant reported the number of hours they spend on the internet in a typical week (the dependent variable). The researcher found the following
- Urban participants reported an average of 8.9 hours of internet use per week with a standard deviation of 2.77.
- Suburban participants reported an average of 12.7 hours of internet use per week with a standard deviation of 4.88.
- Rural participants reported an average of 9.8 hours of internet use per week with a standard deviation of 2.82.
Using the data that was collected, the researcher found the following:
- The sum of squares between groups is equal to 78.86.
- The sum of squares within groups is equal to 354.51.

Each individualis employed in one of four professions (Medical, Legal, Economics and Psychology). Each subject participates in astructured interview, during which the clinical psychologist makes ratings based on fatigue, lethargy, and energy.The data with the results can be found in the sheet labelled “Question 2”.a.

One method uses ultrasound, and the other method uses X-ray technology. Body fat percentages using each of these methods for 16 athletes (a subset of the data given in a graph that appeared in the paper) are given in the accompanying table. You can assume that the 16 athletes who participated in this study are representative of the population of athletes.
