The paper “Contemporary College Students and Body Piercing” (Journal of Adolescent Health [2004]: 58-61) described a survey of 450 undergraduate students at a state university in the southwest region of the United States. Each student in the sample was classified according to class standing (freshman, sophomore, junior, or senior) and body art 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 evidence that there is an association between class standing and response to the body art question. Assume that it is reasonable to regard the sample of students as representative of the students at this university. Use α = .01.
A developmental psychologist who wanted to know if the age when children started walking affected school performance divided 48 children into 16-Early, 16-Middle, and 16-Late Walkers. At the end of the second grade, the psychologist computed a composite school performance score based on teachers' reports. The means and estimated population variances for the three groups were: Early Walkers: M = 33, 52 = 25; Middle Walkers: M = 42 52 = 36; Late Walkers: M = 42. 52 = 16. a.) Is there a difference in school performance score between three walking groups? (Use the.05 level.) Use the five steps of hypothesis testing. Label all the steps clearly. Show ALL Work/calculations. b.) Report the statistic in APA format (the statistical sentence).
