- How do I find the degrees of freedom?arrow_forwardComputer programmers employed by a software developer were asked to participate in a monthlong training seminar. During the seminar, each participant was asked to record the number of hours spent in class preparation each week. After completing the seminar. the productivity level of each participant was measured. A positive linear statistical relationship between participants' productivity levels and time spent in class preparation was found. Based on the information (a) Identify the predictors and response variable Identify three alternative predictor variables that might cause both the employee productivity scores and the employee class participation times to increase (decrease) simultaneously.

Participants in this study were 30 students in an upper-division communications course at Cornell University who received course credit for participation. Participants were asked to record all of their social interactions for a week, making note of any lies told. Based on data from these records, the authors of the paper concluded that students lie more often in phone conversations than in face-to-face conversations and more often in face-to-face conversations than in e-mail. Discuss the limitations of this study, commenting on the way the sample was selected and potential sources of bias. (Select all that apply.)

- A study examined the relationship between a nurse's assessment of a patient's facial expression and his or her self-reported level of pain. Data for 89 patients are summarized below: Self-Report Facial Expression No Pain Pain No Pain 17 40 Pain 3 29 We'd like to determine if there is evidence of an association between a facial expression that reflects pain and self-report pain, because dementia patients do not always give a verbal indication that they are in pain. By using SPSS or Minitab, design the appropriate test and generate the data analyses. Relate the results of the test to the research question and conclude the findings.arrow_forwardTwenty samples of students from the first year were taken for the study related to student emotional intelligence (EQ) in a university.

- Elissa Epel, a professor of health psychology at the University of California-San Francisco, studied women in high- and low-stress situations. She found that women with higher cortisol responses to stress ate significantly more sweet food and consumed more calories on the stress day compared with those with low cortisol responses, and compared with themselves on lower stress days. Increases in negative mood in response to the stressors were also significantly related to greater food consumption. These results suggest that psychophysiological responses to stress may influence subsequent eating behavior. Over time, these alterations could impact both weight and health. You are interested in studying whether college juniors or college sophomores consume more calories. You ask a sample of n, = 35 college juniors and n2 = 40 college sophomores to record their daily caloric intake for a week. The average daily caloric intake for college juniors was M1 2,423 calories, with a standard…arrow_forwardA Canadian study measuring depression level in teens (as reported in the Journal of Adolescence, vol. 25, 2002) randomly sampled 112 male teens and 101 female teens, and scored them on a common depression scale (higher score representing more depression). The researchers suspected that the mean depression score for male teens is higher than for female teens, and wanted to check whether data would support this hypothesis. What conclusion can you draw from the output? The data provide sufficient evidence to reject H0 and to conclude that the mean depression score for male teens is larger than that of female teens. The data provide sufficient evidence to conclude that male and female teens do not differ in mean depression score. The data do not provide sufficient evidence to conclude that the mean depression score of male teens is larger than that of female teens. The data do not provide sufficient evidence to reject H0, so we accept it, and conclude that male and female teens do…arrow_forwardElissa Epel, a professor of health psychology at the University of California–San Francisco, studied women in high- and low-stress situations.

- Researchers study the relationship between interpersonal violence and health in colege age women. The researchers report an OR for the use of analgesics among abused versus non abused women (OR 1.45, 95 % , CI 0.97-2.15). Based on this information, you know: In this study women who were abused were 4.5 times as likely to report analgesic use This is a clinically significant result There is no significant difference in analgesic use for abused and non-abused women Abused women are significantly more likely to use analgesicsarrow_forwardStudies have suggested that alcohol abuse and disorders are found to be more prevalent during early adulthood than in any other age group, with about 9% of young adults (age 18 to 29 years) meeting the criteria to be labeled as alcoholic. In addition, surveys have shown that college students tend to drink more than their peers who do not attend college. You want to test to see if there are differences in excessive alcohol use in young adults that attend college versus those who do not, so you surveyed 405 young adults, age 19 to 22, about their alcohol use by asking the question, "Have you consumed alcohol to the point of intoxication at least once within the past month?" with the following results. Young Adults Attending College Young Adults Not Attending College n1 = 255 n2 = 150 y1 = 96 said "yes" y2 = 44 said "yes" p̂1 = 96 255 p̂2 = 44 150 (a) Calculate the test statistic.
