Project 2 - Frequency Distribution

Using the data file attached - calculate the following using arrays:

1. fequency distribution
2. cummulative frequency distribution
3. relative frequency distribution
4. cummulative relative frequency distribution

Use the following bins to determiine the frequency distribution:
Bins
10 Num of projs less or equal to 10
20 Num of projs 11 - 20
30 Num of projs 21 - 30
40 Num of projs 31 - 40
50 Num of projs 41 - 50
60 Num of projs 51 - 60
70 Num of projs 61 - 70
80 Num of projs 71 - 80
90 Num of projs 81 - 90
100 Num of projs 91 - 100
