The article "Display of Health Risk Behaviors on MySpace by Adolescents"+ described a study in which researchers looked at a random sample of 500 publicly accessible
MySpace web profiles posted by 18-year-olds. The content of each profile was analyzed. One of the conclusions reported was that displaying sport or hobby involvement was
associated with decreased references to risky behavior (sexual references or references to substance abuse or violence).
(a) Is the study described an observational study or an experiment?
an observational study
an experiment
(b) Is it reasonable to generalize the stated conclusion to all 18-year-olds with a publicly accessible MySpace web profile? What aspect of the study supports your answer?
No, it is not reasonable to generalize the stated conclusion since the study didn't include all 18-year-olds on MySpace.
No, it is not reasonable to generalize the stated conclusion since the study was an experiment and you cannot generalize conclusions to…

Participants with doctor-diagnosed arthritis either received a Tai Chi course immediately or were placed in a control group to begin the course 8 weeks later. At the end of the 8-week period, self-reports of pain were obtained for both groups. Data similar to the results obtained in the study are shown in the following table.

- A researcher would like to conduct a study related to student emotional intelligence (EQ) in a university. The researcher would like to examine two objectives in his study. First, he would like to examine whether the EQ training and coaching programme will improve the level of EQ for university students. Second, he would like to study the relationship between student academic performance (CGPA) and students’ emotional intelligence (EQ) in a university. Twenty samples of students from the first year were taken for the study. The researcher has collected the data for a few variables: gender, academic performance, and emotional intelligence (EQ) test score. The study is divided into two parts. First, the student must answer the emotional intelligence (EQ) test assessment before attending the EQ training and coaching programme. Second, the researcher will request the same twenty students to attend a one-month emotional intelligence (EQ) coaching and training programme. Upon completing the…arrow_forward6. Binge-watching a television show might not be the best way to enjoy a television series (Horvath et al., 2017). Participants in an experiment were in a group that either watched an entire tv series during daily one-hour sessions or watched all the episodes during a single binge session. Participants were asked to rate their enjoyment of the t.v. series on a scale of 0-100. Data like those observed by the author are listed below: Binge-watched 87 Daily-watched 84 71 100 73 87 86 97 78 92 a. Is there a difference in the level of enjoyment based on whether the series was binge-watched or watched on a daily basis? Use a two-tailed test at the a = 0.05 level of significance? b.

According to a study released by PwC, 38% of surveyed business and IT executives reported phishing scams at their institutions.Source: Data extracted from “Toward new possibilities in threat management,” PwC, 2017 pwc.to/2kwhPJv. a. If you conduct a follow-up study to estimate the population proportion of business and IT executives reporting phishing scams at their institutions, would you use a p of 0.38 or 0.50 in the sample size formula? b. Using your answer in part (a), find the sample size necessary to estimate, with 95% confidence, the population proportion to within 0.03.arrow_forward

- A sociologist wants to investigate the question, "Is there a relationship between texting during class and grade-point-average (GPA) among high school seniors in a large district?" Which study design is most appropriate? Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester, obtain each student’s GPA from the appropriate admissions and records office. Compare the GPA of students who routinely text during class to the GPA of students who do not text during class. Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester,…arrow_forwardDoes support for assisted suicide (“death with dignity”) vary by social class? Is this relationship dif-ferent in different nations? Small samples in three nations were asked whether it is ever justified for a per-son with an incurable disease to take his or her own life. Respondents answered in terms of a 10-point scale, on which 10 was “always justified” (the strongest support for “death with dignity”) and 1 was “never justified” (the lowest level of support).
