I gathered data from a class where I recorded the number of absences a student had along with their grade on the final exam. The following table shows the data: # absences final exam score 0 94 1 88 2 Find the correlation coefficient r: 75 For each part, round to 3 decimal places. Are the two variables correlated? (Y or N) Find the linear regression line = mx + b: m = 4 67 What grade would you predict for someone with 10 absences? 6 52 b = 8 34 12 15 I gathered data from a class where I recorded the number of absences a student had along with their grade on the final exam.
