Find f(t) for each F(s):

Problem:

Based on an examination given to a large class in which the maximum score is 100 points, assuming that 20 grades taken at random from the entire set produced the results that follow:

43 49 56 61 65 68 70 70 74 74 76 79 80 83 84 87 88 92 96 100

Determine analytically the:

a sample mean

b sample mean-square

c sample rms value

d sample variance

e sample standard deviation

f median

g mode

h range

e compute all the above values using Matlab.
