The data was obtained in a study on the number of absences in the day and the final grades of seven randomly selected students from a statistics class. The data and output of IBM-SPSS software are shown below. Model Student A B C D E F G Absences Grade (Constant) Absences Number of absences 6 2 15 9 12 5 Pearson Correlation Sig. (2-tailed) N Pearson Correlation Sig. (2-tailed) N **. Correlation is significant at the 0.01 level (2-tailed). 8 c) Compute the value of X. B 102.493 X Absences Std.
