The University of cape town aims to evaluate students’ academic performance. In line with this, you have been appointed as a Consultant to work on the project. The University would want to ascertain how age, gender, work experience, interim assessment scores and examination scores influence students’ overall academic performance. In doing so, you are required to provide answers to the following issues to the University in simple, clear and concise form. As much as possible, provide justification for the choice of your answers.
a. Assuming you will have to collect data from the respondents directly, describe the instrumentation you will use. b. Describe the method you will employ in administering the instrument in (a) above.
Jensen Tire & Auto is in the process of deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine. Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars).

Reject H0. We conclude that the relationship between weekly usage (hours) and annual maintenance expense (in hundreds of dollars) is significant.
Do not reject H0. We conclude that the relationship between weekly usage (hours) and annual maintenance expense (in hundreds of dollars) is significant.

When I was a student, I was one of a relative minority who worked in addition to going to classes. That circumstance has changed drastically in the intervening years. According to several recent studies, almost all students work at least part-time, and many work full-time while enrolled in classes (ACE Center for Policy and Analysis, 2006; Alfano and Eduljee, 2013; Perna, 2010). Both faculty and administrators are concerned that the shift in focus to the world outside of school can affect academic performance. We compare the GPA of students who work at least part-time outside of class with those who do not work.

- We've studied two different basic types of research studies, Observational Studies and Experiments. They have similarities and differences in their methodologies, and in some cases it is not practical nor ethical to design a study one way or the other. And this affects the kinds of conclusions the research can ultimately reach. This discussion is designed for students to help each other build a complete understanding, and clearly separate these as two distinct concepts. Discuss the similarities and differences between these, as well as the research conclusions to which they can possibly lead.arrow_forwardIn recent years major efforts have been made to standardize accounting practices in different countries; this is called harmonization. In an article in Accounting and Business Research, Emmanuel N. Emenyonu and Sidney J. Gray studied the extent to which accounting practices in France, Germany, and the U.K. are harmonized. (a) Depreciation method is one of the accounting practices studied by Emenyonu and Gray. Three methods were considered—the straight-line method (S), the declining balance method (D), and a combination of D & S (sometimes European firms start with the declining balance method and then switch over to the straight-line method when the figure derived from straight line exceeds that from declining balance). The data in the table (below) summarize the depreciation methods used by a sample of 78 French, German, and U.K. firms. Depreciation Methods France Germany UK Total A. Straight line (S) 15 0 25 40 B.
