For this problem we are being asked about the \"overall\" relationship between 2 sets of scores, NOT to predict. It is a non-directional, two-tailed problem and to solve, a regression equation is needed. In this problem we are being asked to calculate SEE. A professor claims that scores on the first test provide an excellent predictor of students\' performance throughout the semester. The following are students\' first- exam scores and final grades for twelve (12) students: Please use instructions above and give detailed answers with step by step calculations. a. Is the professor correct? Test with a = 0.05. b. How accurately do the exam scores predict final grades? Compute the standard error of the estimate.
