I understand in this question that you have to take the outlier out. I'm not understanding the steps after that involving the line of best fit and correlation however?

b) Predict the University Average of a student who had a 60 for their High 3. Mr. Kartye wants to investigate if student performance on the MDM 4U final exam is related to time spent studying for the exam. He gathered the following sample data: Hours studying 10 15 21 6 18 20 12 Exam mark 78 85 96 75 84 45 82 Exam Mark Ve. Hours Studying Scatter Plot 100 Exam_Mark 8 8 8 8 8 8 B 10 12 16 18 20 Hours_Studying Residual 10 12 14 16 20 Hours_Studying Exora Mark . -0.197Hours_ Studying + 81; r*2 = 0.0039 Using Fathom, Mr. Kartye generated the scatter plot shown at the right. Unfortunately, it does not display what Mr. Kartye wanted. For example, 2=0.0039 meaning there is absolutely no relationship (correlation) between exam marks and hours spent studying. Furthermore, the line of best fit of yp = -0.197x + 81 demonstrates a negative slope. In other words, the more you study, the lower your exam mark. Kartye determines he must have done something wrong, or not taken something into consideration. Suggest how Mr. Kartye should modify his data set. Implement your suggestion to determine a new line of best fit, and coefficient of determination
