A significant interaction was found between depression, social support and GPA. These results should be considered with caution and further research should be done to better understand the relationships between these variables. Furthermore, those working with college students should consider the overall well-being of the student, as it is possible that their academic performance may not be affected by anxiety and/or depression.

- The article "Americans are 'Getting the Wrong Idea' on Alcohol and Health"† reported that observational studies in recent years that have concluded that moderate drinking is associated with a reduction in the risk of heart disease may be misleading. The article refers to a study conducted by the Centers for Disease Control and Prevention that showed that moderate drinkers, as a group, tended to be better educated, wealthier, and more active than nondrinkers. Explain why the existence of these potentially confounding variables prevents drawing the conclusion that moderate drinking is the cause of reduced risk of heart disease. (Select all that apply.) Someone who is more active is more likely to avoid healthier food. Someone who is wealthier is more likely to purchase healthier food. Someone who is more active is more likely to seek out healthier food. Someone who is educated is more likely to seek out healthier food.

- Since this research focuses on sleep habits in college students and its effect on mental health, we have proposed the research question to be what the prevalence of college student's mental health issues are due to poor sleeping habits.Previous research has shown that anxiety and depression can be two indicators of poor sleep habits in college students (Becker et al., 2018). As mentioned before, college students are also at risk of developing poor sleep habits because, as freshmen, they transition into a more significant workload than they are accustomed to doing. They are also given more freedom with their time. So, we predict a relationship between mental health and low amounts of sleep-in students. In contrast, the alternative outcome is that there will be no mental health problems arising as students lose sleep for long periods. Since getting good sleep allows us to function better throughout our days, we will likely see the impact bad quality and quantity of sleep will have on…A researcher assesses work ethic among college students using a self-report questionnaire. Moreover, the researcher tracks how many hours students seek out extra support at the tutoring center and with their professors on campus during the semester. The researcher determines that there is a significant positive relationship between self-reported work ethic and the number of hours students seek out extra support at the tutoring center and with their professors during the semester. This demonstrates how correlations can be used to demonstrate _____.Most sports injuries are immediate and obvious, like a broken leg. However, some can be more subtle, like the neurological damage that may occur when soccer players repeatedly head a soccer ball. To examine effects of repeated heading, McAllister et al. (2013) examined a group of football and ice hockey players and a group of athletes in noncontact sports before and shortly after the season. The dependent variable was performance on a conceptual thinking task. Following are hypothetical data from an independent-measures study similar to the one by McAllister et al. The researchers measured conceptual thinking for contact and noncontact athletes at the beginning of their first season and for separate groups of athletes at the end of their second season. Before the first season After the second season Contact Sport n = 20 M = 9 n = 20 M = 4 Noncontact Sport n = 20 M = 9 n = 20 M = 8 For the first four blanks, choose from the following and enter the…

Be sure to include a discussion of statistical inference.wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight? Use a significance level of α=0.05. Correlation Results Correlation coeff, r: 0.978552 Critical r: ±0.2680855 P-value (two tailed): 0.000
- A researcher is interested in gender differences in attitudes toward dating. Specifically, she wants to test the hypothesis that women are more accepting than men are of the idea that men should always pay on the first date, and thus women should have a more traditional view of dating than men do. Data are collected from 10 women and 10 men using a scale that measures dating behaviors and attitudes. Higher scores mean more traditional dating attitudes. Answer the following: 1) What are the independent and dependent variables in this study? 2) What inferential statistic discussed thus far could be used to answer this question? 3) Discuss your process of answering questions one and two.Does posting calorie content for menu items affect people’s choices in fast-food restaurants? According to results obtained by Elbel, Gyamfi, and Kersh (2011), the answer is no. The researchers monitored the calorie content of food purchases for children and adolescents in four large fast-food chains before and after mandatory labeling began in New York City. Although most of the adolescents reported noticing the calorie labels, apparently the labels had no effect on their choices. Data similar to the results obtained show an average of M =786 per meal with s = 85 for n =100 children and adolescents before the labeling, compared to an average M = 772of with s =91 for a similar sample of n = 100 after the mandatory posting. Use a two-tailed test with alpha = .05 to determine whether the mean number of calories after the posting is significantly different than before calorie content was posted.Do less agreeable Facebook users tend to spend more time on Facebook? A study (Ivcevic and Ambady, 2013) aimed to investigate various facets of use of the social networking website Facebook. Previous research suggested that individuals with poorer face-to-face social skills may find internet-based social platforms less daunting, so as part of the study Ivcevic and Ambady investigated whether an individual's volume of Facebook use was associated with levels of "agreeableness". The subjects were 99 university students who all had a Facebook page. The subjects agreed to allowing the content of their Facebook pages to be downloaded on six separate occasions over a three-week period. As part of the data gathered on each subject, each of the 99 were individually rated by a selected friend on an "agreeableness" scale (based on average ratings on a questionnaire where all responses were on a Likert scale), with 1 being "low" and 5 "high". We consider here the relationship between "friend…
