Question
Assume that we find a positive correlation between the number of hours students spend studying for a test and their grade on the test. If we calculate the regression equation for these data and find that the y intercept is 65, what conclusion can we draw?
The standard error of the estimate is low.
The regression line crosses the x axis at a score of 65.
The slope of the regression line is 65.
When students do not study at all, we would predict a score of 65 on the exam.
a.The standard error of the estimate is low.
b.The regression line crosses the x axis at a score of 65.
c.The slope of the regression line is 65.
d.When students do not study at all, we would predict a score of 65 on the exam.
Explanation / Answer
y - intercept indicates the value of y when value of X is 0. Hence,
When students do not study at all, we would predict a score of 65 on the exam.
Option d is correct.
