Frequency Numbers for Data Representations

The data represents the daily rainfall (in inches) for one month. Construct a frequency distribution beginning with a lower class limit of 0.00 and use a class width of 0.20. Does the frequency distribution appear to be roughly a normal distribution?

0.39 0 0 0.29 0 0.54
0 0.17 0 0 1.25 0
0.16 0 0.02 0 0.21 0
0.13 0.46 0 0.01 0 0.22
0 0.21 0 0 0.23 0

Daily Rainfall (inches) Frequency Daily Rainfall (inches) Frequency
0.00-0.19 24 0.80-0.99 0
0.20-0.39 6 1.00-1.19 0
0.40-0.59 2 1.20-1.39 1
0.60-0.79 0

The numbers are correct but can you explain to me how you get the frequency numbers?

Solution Preview

Let me expand on this a bit. So the buckets were derived as follows. Instructions read "beginning with a lower class limit of 0.00 and use a class width of 0.20. This basically means we want to set up intervals beginning with 0.00, incremented by 0.20. Thus, your buckets begin with 0.00, 0.20, 0.40, etc. and end with the beginning of the next interval.

By the term "frequency", you can probably guess that basically frequency is the number of occurrences that fall in the ...
