Using a Matlab plot the marks distribution of 62 students using histogram graph. The marks obtained by these students are [63 55 81 48 91 63 65 65 69 20 66 50 61 50 68 73 93 50 71 66 53 63 68 73 60 90 90 73 70 85 68 65 88 60 43 66 71 75.5 63 49 74 78 60 81 65 50 49 68 49 50 55 95 53 96 72 55.5 90 94 59 43 55 75]. Set the histogram bin limits from 0 to 100, number of bins = 20, and bin width of 5. Label the title, x and y axis appropriately. Based on the histogram answer following questions:

1. How many students occupies in the average range and what is the average range for this histogram?
2. How many students got marks higher than 80%?
3. How many student got marks below than 50%?
