Back in the day, in a class of 25 students, a statistics professor created a linear regression to predict a student’s overall points earned on a test (y) from their score on one particular problem (x). She found that the regression line, framed as we usually do in class, was given by

y = 48.208 + 2.518(x − 8.625)

and that the sum of the squares of the differences of the actual values of y and the values predicted by the regression line was 1664.175. Use this information to calculate a 95% confidence interval for α.

In a statistics course, a linear regression equation was computed to predict the final-test score from the score on the first quiz. The resulting equation was: ˆy = 25 + 0.84x with a correlation of 0.73 where y is the final test score and x is the score on the first quiz.

Suppose we have collected the midterm and final scores of 200 students in a Statistics class, and we observed that the scatter plot of final scores versus midterm scores is roughly linear. Suppose the average midterm score is 76, with SD 12, and the average final score is 71, with SD 10. Suppose the correlation coefficient between midterm and final scores is 0.6. Use the regression line, or an equivalent regression procedure, to predict the final score for someone who...

The table below gives the number of absences and the overall grade in the class for five randomly selected students. Based on this data, consider the equation of the regression line, yˆ=b0+b1x, for using the number of absences to predict a student's overall grade in the class. 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...
