A 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."

As you read about each​ study, (a) classify the type of research that it​ reflects, and​ (b) identify the kinds of conclusions that might reasonably be drawn from the results. During their​ 8th- and​ 11th-grade school​ years, students in the Ranger School District take standardized achievement tests designed to assess their language and math skills. The superintendent receives a report showing how Ranger students compare with those in many other school districts across the nation. The superintendent discusses the results with the school principals. ​(a) Classify the research as one of the​ following:   ​Quantitative/descriptive   ​Quantitative/correlational   ​Quantitative/experimental   ​Quantitative/quasi-experimental   Qualitative   Mixed​ methods, and then ​(b) Identify one or more conclusions that might reasonably be drawn from this study​ and, if​ relevant, one or more conclusions that cannot be drawn from the study

Physician Specialty. According to the document Physician Specialty Data Book, published by the Association of American Medical Colleges, in 2010, 12.9% of active male physicians specialized in internal medicine and 15.3% of active female physicians specialized in internal medicine. Does an association exist between the variables “gender” and “specialty” for active physicians in 2010? Explain your answer.

Can I get some help with identifying the variables and individuals?

Paragraph Styles 7. In recent years, researchers have differentiated between two types of internet harassment: cyberbullying and Internet trolling. In a recent study of cyber harassment, a large sample of online participants answered survey questions related to personality, cyberbullying history, and Internet trolling. Below are scores that capture the relationship between cyberbullying and internet trolling observed by the authors: TTT Cyberbullying score 2 Internet trolling score Participant A 1 4 7 7 E 9 8 a. Is there a significant relationship between cyberbullying and trolling scores? Test at an alpha level of .05. c. Create a graph of your results that is appropriate for this type of analysis 17

Seedlings of an annual plant were split into two equal treatment groups; in one group, extra fertilizer was provided, and in the other group (the control group), no additional fertilizer was added. The numbers of seeds and the average weight of the seeds from each individual plant were monitored, and these data were plotted (each point represents an individual plant). Which statement best describes the results of this study? Control With fertilizer 450 400 400 350 350 300 300 250 250 200 200 130 130 100 100 50 50 10 20 30 40 50 70 10 20 30 40 50 Number of seeds Number of seeds O A. Trade-offs between seed size and seed number exist in both the control and the fertilizer groups, and these trade-offs are of roughly equal magnitude. B. Trade-offs between seed size and seed number exist in both the control and the fertilizer groups, but these trade-offs are much larger in the fertilizer group. C.A trade-off between seed size and seed number exists in the control group but not in the…

Some research situations are summarized below. For each situation, identify all variables.Then, for each variable, note the level of measurement AND whether it is an independent or dependent variable.         a.Ahealth researcher is interested in studying patient compliance (whether or not patients take the medicine their doctor prescribes). She surveys 800 diabetic patients, and finds compliance to be linked to patient age, education, gender, and socioeconomic status. b. A market researcher is hired by Target to see how customers buying habits have changed before and after COVID.  The researcher studies how much each customer spent (in $s), how frequently they visited the website each month, how frequently they visited the store each month.  They report that, since March, customers are spending less, visiting the website more frequently, and shopping in person less frequently.

The business problem facing the director of broadcasting operations for a television station was the issue of standby hours (i.e. hours in which unionized graphic artists at the station are paid but are not actually involved in any activity) and what factors were related to standby hours. A study of standby hours was conducted for 26 weeks. The variables in the study are described below and the data from the study are shown in the accompanying table. Complete parts a throughg below. Standby hours (Y)-Total number of standby hours in a week Total staff present (X,)-Weekly total of people-days Remote hours (X,)-Number of hours worked by employees off-site E Click the icon to view the data table.
