There is some evidence that high school students justify cheating in class on the basis of poor teacher skills or low levels of teachercaring (Murdock, Miller, & Kohlhardt, 2004). Students appear to rationalize their cheating behavior based on perceptions of how theirteachers view cheating. Poor teachers are thought not to know or care whether students cheat, so cheating in their classes is okay.Good teachers, on the other hand, do care and are alert to cheating, so students tend not to cheat in their classes.The scores below represent judgments of the acceptability of cheating for the students in each sample (a higher number means it ismore acceptable to cheat). Is there a difference in the student ratings of how acceptable it is to cheat based on teacher type?Use an ANOVA with a = .05 to determine whether there are any significant differences among the three types of teachers in theacceptability of cheating based on student ratings.

Applicants for temporary office work at Carter Temporary Help Agency who have successfully completed an administrative assistant course are then placed in suitable positions by Nancy Dwyer and Darla Newberg. Employers who hire temporary help through the agency return a card indicating satisfaction or dissatisfaction with the work performance of those hired. From past experience it is known that 75% of the employees placed by Nancy are rated as satisfactory, and 65% of those placed by Darla are rated as satisfactory. Darla places 60% of the temporary office help at the agency, and Nancy places the remaining 40%. If a Carter office worker is rated unsatisfactory, what is the probability that he or she was placed by Darla? (Round your answer to three decimal places.)
A researcher wants to investigate whether mindfulness training improves ability for employees to notice positive experiences in the workplace, and if this differs by gender and/or disposition. Employees were randomly assigned to one of two groups: no training or a half-day session. Gender was categorized as male or female. Disposition was categorized as follows: optimist, pessimist or realist. Ability to notice positive experiences in the workplace was quantified using a Likert-based ambulatory assessment. A factorial design was used to analyze the data. Question: How many null hypotheses (and thus, F-ratios) are there in this scenario?
Some researchers have noted that adolescents who spend a lot of time playing video or computer games are at greater risk for depression and violence. This is an example of: a. an observational study with lurking variables that may explain the association. b. a paired data experiment, because we are studying both aggression and game playing. c. a single-blind experiment, because the subjects knew they were playing games. d. a valid conclusion, because more time yields more aggression is a positive association.

2.- The journal Behavioral Research in Accounting published a study of Machiavellian traits in accountants. Machiavellian describes negative character traits that include manipulation, cunning, duplicity, deception, and bad faith. A questionnaire by email was administered to a random sample of 700 accounting alumni of a large southwestern university; however, due to nonresponse and incomplete answers, only 198 questionnaires could be analyzed. Several variables were measured, including age, gender, level of education, income, job satisfaction score, and Machiavellian (“Mach") rating score. The research findings suggest that Machiavellian behavior is not required to achieve success in the accounting profession. a) What is the populatidn of interest to the researcher? Answer: Business accountants in the southwest Accountants in general Accounting alumni from this university Business alumni from this university b) What inference was made by the researcher? Answer: Accountants are always…

Bullying,” according to noted expert Dan Olweus, “poisons the educational environment and affects the learning of every child.” Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure anxiety in a group of bullies and a group of victims using an 18-item, 5-point anxiety scale. Assume scores on the anxiety scale are normally distributed and that the variances of the anxiety scores are the same among bullies and victims. The group of 23 bullies scored an average of 40.1 with a sample standard deviation of 10 on the anxiety scale. The group of 28 victims scored an average of 46.8 with a sample standard deviation of 11 on the same scale. You do not have any presupposed assumptions about whether bullies or victims will be more anxious, so you formulate…
Do ethnic group and gender influence the type of care that a heart patient receives? The following pas- sage is from the article “Heart Care Reflects Race and Sex, Not Symptoms” (USA Today, February 25, 1999, reprinted with permission):Previous research suggested blacks and women were less likely than whites and men to get cardiac cathe- terization or coronary bypass surgery for chest pain or a heart attack. Scientists blamed differences in illness severity, insurance coverage, patient preference, and health care access. The researchers eliminated those differences by videotaping actors—two black men, two black women, two white men, and two white women—describing chest pain from identical scripts. They wore identical gowns, used identical gestures, and were taped from the same position. Researchers asked 720 primary care doctors at meetings of the American College of Physicians or the American Academy of Family Physicians to watch a tape and recommend care. The doctors thought the…
24) Some research has shown that swearing can help reduce ratings of pain (Stephens, Atkins, & Kingston, 2009). In one such study, each participant was asked to plunge a hand into icy water and keep it there as long as the pain would allow. In one condition, the participants repeated their favorite curse words while their hands were in the water. In the other condition, the participants repeated a neutral word. In addition to lowering the participants’ perception of pain, swearing also increased the amount of time they were able to tolerate the pain. Data similar to the results obtained in their study are shown in the following table. Amount of Time (in Seconds) Participant Swear Words Neutral Words 1 94 59 2 70 61 3 52 47 4 83 60 5 46 35 6 117 92 7 69 53 8 39 30 9 51 56 10 73 61 Do these data indicate a significant difference in pain tolerance between the two conditions?…
Five percent of the customers who visit a website complete a product purchase. If one considers just the set of customers who completed the project purchase at the website, 80% read at least some of the user reviews about the product on the site. When considering those customers who did not purchase of the product at the website, only 20% of these potential customers read the user reviews about the product on the site. The website managers are interested in how customer review-reading behavior affects the likelihood of purchase. A likelihood probability for this problem context is: A. P(Purchase | Visit Site) B. P(Did Not Purchase | Read User Reviews) C. P(Visit Site | Purchase) D. P(Did Not Read User Reviews | Product Purchased) E. None of the answers are correct.
