Answer:
Option A) As the Exam 1 score increases by 1 point, the student's Exam 3 grade will increase, on average, by 0.4845 points.
Step-by-step explanation:
We are given the following in the equation:
A simple linear regression analysis was conducted to predict the Exam 3 score of students in STA 2023 based on their Exam 1 score.
Thus, Exam 3 score becomes the dependent variable and exam 1 score is the independent variable.
The regression equation is given by:
Comparing the equation to a linear equation:
m = 0.4845
c = 50.57
Where m is the slope and tells the rate of change and c is the y intercept that is the value of y when x is 0.
When, there is a increase in x, we can write:
Thus, the slope of equation can be interpreted as:
Option A) As the Exam 1 score increases by 1 point, the student's Exam 3 grade will increase, on average, by 0.4845 points.
