3.17 The vector G=[68, 83, 61, 70, 75, 82, 57,5, 76, 85, 62, 71, 96, 78, 76, 68, 72, 75, 83, 93] represents the distribution of final grades in a dynamics course. Compute the mean, median, mode, and standard deviation of G. Which better represents the most typical grade, the mean, median, or mode? Why? Use MATLAB to determine the number of grades in the array (don't just count them) and to sort them into ascending order
