2) Histogram Assume, the total number of points in examination was 100. The 50 participants achieved the following results. 4 12 25 26 27 35 38 42 43 45 51 51 51 52 53 54 55 56 57 59 59 59 60 60 60 61 62 62 62 63 64 64 65 66 67 68 68 70 72 72 73 74 76 79 80 82 84 87 95 98 The bins are defined as follows. Bin 1: result < 24 points, Bin 2: result > 24 points and result = 49 points Bin 3: result > 49 points and result = 64 points Bin 4: result > 64 points and result < 79 points Bin 5: result > 79 points and result < 89 points Bin 6: result > 89 points and result < 100 points. a) Calculate the absolute frequencies, the relative frequencies and the heights of the blocks of the corresponding histogram. b) Draw the histogram.
