The grаdes оf а clаss оf 10 students оn a midterm exam (x) and on the final exam (y) are as follows: Midterm (x) 77 49 71 73 81 94 97 99 70 82 Final (y) 82 66 78 34 65 84 96 99 65 99 A simple linear regression is fit to this data set to estimate the final exam grade (y) from the midterm exam grade (x). Determine the lower limit and upper limit of a 90% prediction interval for the final exam grade of a single student who scored a 91 on the midterm exam. Show your work. Lower Limit of 90% Prediction Interval: Upper Limit of 90% Prediction Interval:
