The equation of the best fit line relating x, the number of absences, to y, the final grade is y with hat on top equals 0.449 x minus 30.27. Student A missed 7 classes while student B missed 25 classes. Assuming that the scope of the model is between missing 0 classes to 30 classes, the predicted Final Grades for these grades are as follows: Student A: 76.854; Student B: 27.264 Student A: 89.33; Student B: 50.235 Student A: 76.854;...

The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would...

Consider the following estimated multiple regression model relating GPA to the number of classes attended and the final exam score in a particular class, and if the student is a freshman (=1 if freshman, =0 otherwise). GPA = -0.3507+0.1096(Attendance) + 0.1697(Exam Score) -0.1380(Freshman) Suppose two students, one a junior and one a freshman, attended the same number of classes and both got a score of 88 on the final exam. What would be the expected difference in the GPa for...
