Answer:



Step-by-step explanation:
Given
See attachment for cumulative frequency histogram
Solving (a): Swimmers between 200yd and 249yd
To do this, we simply read the data from the 0 mark
From the histogram, we have:

and

So:

This gives:


Solving (b): Swimmers between 150yd and 199yd
To do this, we simply read the data from the 0 mark
From the histogram, we have:

and

So:

This gives:


Solving (c): Total swimmers
To do this, we simply read the longest bar of the histogram

Hence:

Answer:10^8
