Answer #1

We define the variables in SPSS like this: HOURS = hours of studying and GPA = GPA score. We calculated the correlation value between these two variables by running the following SPSS code.

CORRELATIONS
   /VARIABLES=HOURS GPA
   /PRINT=TWOTAIL NOSIG
   /MISSING=PAIRWISE.

The correlation value is coming out to be as 0.1442. The correlation is low because if we draw a scatterplot using the two variables, we will see that the points are scattered. This tells us that the GPA scores are not so much related to how much hours do students take to study.

We study the relation between students' GPA and the number of hours per week spent studying. To this end, we consider the following regression model, GPA = β 0 + β 1 hours+u where GPA is the variable measuring students' GPA, hours is the variable measuring the number of hours studying, and u is the error term. We found the following OLS estimates: β ^ 0 = 2.67 β ^ 1 = 0.601 What is the predicted GPA of a...
