New research suggests that watching television especially medical shows such as grays' anatomy and house can result in more concern about personal health. Surveys administered to college students measure television viewing habits and health concerns such as fear of developing diseases and disorders seen on television. For the following data, students are classified into three categories based on their television viewing patterns and health concerns are measured on a 10-point scale with "0" indicating "none."
Television Viewing
Little or none- 4,2,5,1,3,7,4,4,8,2
Moderate- 5,7,3,4,8,6,2,7,3,5
Substantial- 5,7,6,6,8,9,6,4,6,8

There is some research indicating that college students who use Facebook while studying tend to have lower grades than non-users (Kirschner & Karpinski, 2010). A representative study surveys students to determine the amount of Facebook use during the time they are studying or doing homework. Based on the amount of time spent on Facebook, students are classified into three groups and their grade point averages are recorded. The following data show the typical pattern of results.

Use an ANOVA with α = .05 to determine whether there are significant differences among the three groups. If applicable, perform a Tukey's HSD to determine the nature of the differences.

Judge and Cable (2010) report the results of a study demonstrating a negative relationship between weight and income for a group of women professionals. Follwoing are data similar to those obtained in the study. To simplify the weight variable, the women are classified into five categories that measure the actual weight relative to height, from 1 - thinnest to 5 - heaviest. Income figures are annual income (in thousands), rounded to the nearest $1,000.
A. Calculate the Pearson correlation for these data.
B. Is the correlation statistically significant? Use a two-tailed test with α = .05.
