Question

Please show work so that I can see the process also

Let’s say you scored a 111 on exam 1 and you scored an 125 on exam 2. You can predict your final exam score with the following prediction equation: Y’ = bX + c (round to nearest whole number). X is the total number of points you earned on the first two tests. Given: Mean = 120; standard deviation of y = 100. The correlation (r) between the total score on the first two exams and the final is .89; b =.5567; c=4. Determine the following:

1. Predict your final exam score = ___________________________

2. What is the standard error estimate = _____________________

      bb. What does that number mean? _____________________________________________________________________________________________________________________________________________________________________________________________________________________

3. How likely (denoted as a percentage) is it that you will score less than a score of 111 on the final exam? ________________________________________________________________________________________________________________________________________
