28. A of 100 students were surveyed about their interest in a new Economics major. Interest was measured in terms of high, medium, or low. In the study, 30 students responded high interest, 50 students responded medium interest, and 20 students responded low interest. What is the best way to illustrate the relative frequency of student interest? Interest is a qualitative, nominal variable. The relative frequencies for a qualitative, nominal variable are best summarized with a pie chart.

Topic: Graphic Presentation of Qualitative Data 29. The monthly salaries of a sample of 100 employees were rounded to the nearest $10. They ranged from a low of $1,040 to a high of $1,720. If we want to condense the data into seven classes, what is the most convenient class interval? ($1720 - 1040)/7 = $97.14. Of the answer choices, a interval of $100 is closest to 97.14.

The survey instrument asked students to identify themselves as a Democrat or a Republican. This question is flawed because:
