A professor at Fanshawe college recently published a research paper that aimed to determine whether or not a student's attendance was a reliable predictor of the their final grade. Using the NUMBER OF CLASSES ATTENDED as the explanatory variable and the student's FINAL GRADE (in percent) as the response variable, the professor's paper contained the following statistics:

r = 0.54r-squared = 0.29y = 14.56 + 1.63xt-score = 0.643p-value = 0.0859

a) Interpret the value of the Pearson correlation coefficient.
