- An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently.Tvo alternative loading/unloading methods have been proposed. To account for potential differences due to the type of the ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use a = .05.Stephens, atkins, and Kingston, 2009 conducted an experiment in which participants were able to tolerate moore pain when they were shouting their favorite swear word than when they were shouting neutral words, Identify the dependent and independent variables for this studyStudents in QSO 510 are assigned to observe the effect of various types of music on relaxation mood in patients who are in the early and middle stages of Alzheimer's disease at a certain Nursing Home facility. A number of patients were selected to participate in the study based on their stages of Alzheimer's disease. Three forms of music were tested: R&B, Blues, and Reggae. While listening to music, relaxation levels were recorded for the patients with a high score indicating a higher level of relaxation. Scores are recorded below.

- A research article on the effect of multitasking on grade performance describes an experiment in which 62 undergraduate business students were randomly assigned to one of two experimental groups. Students in one group were asked to listen to a lecture but were told that they were permitted to use cell phones to send text messages during the lecture. Students in the second group listened to the same lecture but were not permitted to send text messages. Afterwards, students in both groups took a quiz on material covered in the lecture. Data from this experiment are summarized in the accompanying table.A restaurant manager conducts a survey to find if there is any relationship between service quality rating and income level of his guests. the income is classified as low, medium, High and the quality of service as poor, good or excellent.

Thomas Boyce, a professor and pediatrician at the University of British Columbia, Vancouver, has studied interactions between individual differences in physiology and differences in experience in determining health and well-being. Dr. Boyce found that some children are more sensitive to their environments. They do exceptionally well when the environment is supportive but are much more likely to have mental and physical health problems when the environment has challenges. You decide to do a similar study, conducting a factorial experiment to test the effectiveness of one environmental factor and one physiological factor on a physical health outcome. As the environmental factor, you choose two levels of stressful life events. As the physiological factor, you choose three levels of immune reactivity. The outcome is number of respiratory illnesses in the previous 12 months, and the research participants are kindergartners.

- If there is an interaction between the variables of “activity level” and “time of day,” this means that activity level does not have the same effect at different times of day. Group of answer choices True FalseA study investigated the relationship between audit delay and variables that describe the client and the auditor. The file Audit contains data from a sample of 40 companies on the following set of variables: Delay: The length of time from a company's fiscal year-end to the date of the auditor's report. Industry: A dummy variable coded 1 if the firm was an industrial company or 0 if the firm was a bank, savings and loan, or insurance company. Public: A dummy variable coded 1 if the company was traded on an organized exchange or over the counter; otherwise coded 0. Quality: A measure of overall quality of internal controls, as judged by the auditor, on a five-point scale ranging from "virtually none" (1) to "excellent" (5). Finished: A measure ranging from 1 to 4, as judged by the auditor, where 1 indicates "all work performed subsequent to year-end" and indicates 4 "most work performed prior to year-end." Click on the datafile logo to reference the data. Consider a model in which…Motivational speakers want to be perceived as trustworthy. One hypothesis is that speakers who exhibit immediacy behaviors such as making eye contact, smiling and leaning forward might be perceived as more trustworthy than those who do not engage in these behaviors. To test this hypothesis, a psychologist obtained data from 26 participants. For people in a non-immediacy group, the speaker did not engage in any immediacy behaviors. For the immediacy group, however, the speaker made eye contact, smiled and leaned forward while giving a speech. After the speech, participants rated the speaker on a scale of trustworthiness ranging from 1 (not at all trustworthy) to 9 (highly trustworthy). The following data were obtained. Test whether the immediacy behaviors of the speaker affect trustworthiness rating. No immediacy behavior Immediacy behavior 4 4 7 4 5 3 6 5 3 5 9 8 4 6 8 7 6 3 8 6 7 5 7 8 7 6…
