Problem 5 (25 points): MATLAB script-5 Create a .m file (script file) that will determine the number of students who received exam averages within each grade band (A,B,C,D,F). Using the examgrades.mat dataset embedded within MATLAB complete the following: (1) Three student exam grades were entered incorrectly, fix them: a. Replace student 45 exam 2 with a 65 b. Replace student 89 exam 4 with a 91 c. Replace student 111 exam 5 with a 98 (2) Students 100 and 117 dropped the course, remove them from the records. (3) Create a new variable ExamMeanLD where in one line you calculate each student's exam average after dropping their lowest exam score. a. Tip: Use element-by-element addition and division b. Required: Use the min function i. Provide 3 arguments within the min function to get what is needed (4) Count the number of student exam averages between each grade band using the following variable names: a. countA which are scores 90+ b. countB which are scores 80-89.99 c. countC which are scores 70-79.99 d. count which are scores 60-69.99 e countF which are scores less than 60 (5) For each grade band use fprintf to print out the number of exam averages within that grade band in integer form, for example: a. There were X students that had an exam average of 90+
