Answer:
The table is attached below and ogive also.
Step-by-step explanation:

The following distribution is given below
First we find the cumulative frequency.
And then we convert it into a less than type ogive.
find the cumulative frequency shown below clearly
And convert it into less than type of cumulative frequency distribution is also done in next table, the daily income is less than daily income upper limit.
In this graph x-axis is daily income and y-axis is number of workers
655 rounded to the nearest hundred would be 700, so that could be an answer but some teachers say that you still have to keep the other digits. So it could be 700 or 1,766,700
