Question 11 Linear Regression Below is data on how many absences a student has each semester in a Statistics class and their overall average for the class: Absences for semester (a): 0 3 5 10 Overall grade (y): 95 80 65 30 T y=mx+b y= < > a.) Would you say the data has a Positive correlation or Negative correlation? O Negative O Positive b.) Compute Ex, Ey, Ex², Exy ΣΧ. = c.) Find the slope and the y-intercept of the best fit regression line. (round to 2 decimal places on slope and y-int) Zy= X+ 17.14/20 pts 9917 Details [x² = Round to nearest % Exy d.) Based on your answer from part c, what would you estimate the Overall average is for students who are absent 6 days in a semester?
