Question
The table below gives the number of hours five randomly selected students spent studying and their corresponding midterm exam grades. Using this data, consider
the equation of the regression line, y = bo + b₁x, for predicting the midterm exam grade that a student will earn based on the number of hours spent studying. Keep
in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the
regression line to make a prediction if the correlation coefficient is not statistically significant.
Hours Studying 2 3
Midterm Grades 71 72
Step 2 of 6: Find the estimated y-intercept. Round your answer to three decimal places.
