I need to write a Java program that takes the names and grades of students and outputs their name, the letter grade, and the Z grade. For this program the letter grade is determined by the following cut-offs: A>=1.0, 1.0 > B>=0.0, 0.0 > C>=-1.0, -1.0 > D>=-2.0, -2.0 > F The z-score depends on the mean and the standard deviation. It is calculated by subtracting the population mean from an individual raw score and then dividing the difference by the population standard deviation. The student letter grade for the assignment is based on how many standard deviations away from the mean that student number grade is. Sample input and output is shown in the picture.
