Hello,
I need help answering the following questions.
- What type of question is this-estimation or hypothesis?
- What type of study is this sample data or experiment data?
- What type of data is this? Univariate or bivariate? Categorical or Numerical?
- How many samples or treatments?
490 undergraduate students at a state university in the southwestern region of the United States were surveyed. Each student in the sample was classified according to class standing (freshman, sophomore, junior, or senior) and body are category (body piercings only, tattoos only, both tattoos and body piercings, no body art). Use the data in the accompanying table to determine if there is an association between class standing and body art category. Assume that it is reasonable to regard the sample as representative of the students at this university. Use α = 0.01.
Freshman Sophmore Junior Senior
Body Piercings 61 7 14 86
Only Tattoos 43 11 10 64
Only Mildly Piercings and Tattoos 20 9 7 43
