Test the significance of correlation coefficient and least square regression equation.
CORRELATION & REGRESSION: Dr. A. Nova wanted to test his theory that there was a relationship between one's attendance and one's performance on his Sadistics exams. He tracked the number of days absent for each of his students this term along with their course averages (shown below). Test whether there is a correlation between the two at a .05 significance level. Also use the regression model to predict a student's average if he/she misses 4 classes. BE PREPARED TO ANSWER SIX QUESTIONS REGARDING THE OUTPUT.
