Another researcher was interested in examining academic
performance among teenage students. However, based on her
literature review, she expected that ethnicity, parental support,
and stress level would predict academic performance. Further, her
study was based in New York.
Therefore, she collected data from one hundred and fifty (150)
students from a school in New York. She hypothesized that parental
support would positively predict academic performance, while stress
would negatively predict academic performance. She also
hypothesized that ethnicity would predict academic...

4.3 The paper "The Relationship Between Cell Phone Use, Academic Performance, Anxiety, and Satisfaction with Life in College Students" (Computers in Human Behavior [2014]: 343-350) described a study of cell phone use among under- graduate college students at a large, Midwestern public university. The paper reported that the value of the correla- tion coefficient between Cell phone use (measured as total amount of time (in hours) spent using a cell phone on a typical day) and y GPA (cumulative grade...

A Massachusetts study of teens found that there is a moderately strong association between the number of hours of physical activity and scores on English and Language Arts state tests. a. Explain in this context what “moderately strong association” means. b. Hoping to improve student performance, the school board passed a resolution urging parents to increase the number of hours that students are physically active. Do you agree or disagree with the school board’s reasoning? Explain. Make sure to comment...

A study was conducted to determine whether there were significant differences between medial students admitted through special programs (such as affirmative action) and medical students admitted with regular admissions criteria. It was found that the graduation rate was 90% for the medical students admitted through special programs. a) 10 of the students from the special programs are randomly selected. Explain why the Binomial distribution is appropriate to describe the random variable X that counts the number of students from the...
