Let's say you scored a 111 on Exam 1 and you scored a 125 on Exam 2. You can predict your final exam score with the following prediction equation: Y' = bX + c (round to the nearest whole number). X is the total number of points you earned on the first two tests. Given: Mean =120, Standard deviation = 100. The correlation (r) between the total score on the first two exams and the final is 0.89, b =...
