A study is conducted on the relationship of the number of absences (x) and the grades (y) of 15 students in Statistics. Using r at 0.05 level of significance and the hypothesis that there is no significant relationship between absences and grades of the students in statistics, determine the relationship using the following data. What is the r (Pearson Product Moment Coefficient of Correlation) ?

(X) 1 2 2 3 3 8 6 1 4 5 5 1 2 1 9

(y) 90 85 80 75 80 65 70 95 80 80 75 92 89 80 65

Suppose we want to predict the grade (y) of the student who has incurred 7 absences (x). Predict y when x=16. What is regression model?
