- Question 1: The University of Professional Studies, Accra (UPSA) 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. Formulate a topic for this project b. State the dependent variable and THREE Independent variables you would consider for the study. c. Identify the population you would use in the conduct of the study.

Many animals, including humans, tend to avoid direct eye contact and even patterns that look like eyes. Some insects, including moths, have evolved eye-spot patterns on their wings to help ward off predators. Scaife (1976) reports a study examining how eye-spot patterns affect the behavior of birds. In the study, the birds were tested in a box with two chambers and were free to move from one chamber to another. In one chamber, two large eye-spots were painted on one wall. The other chamber had plain walls. The researcher recorded the amount of time each bird spent in the plain chamber during a 60-minute session. Suppose the study produced a mean of M =37 minutes in the plain chamber with SS = 288 for a sample of n = 9 birds. (Note: If the eyespots have no effect, then the birds should spend an average of μ=30 minutes in each chamber.) Is this sample sufficient to conclude that the eye-spots have a significant…
