Question

At a meeting of information systems officers for regional offices of a national company, a survey was taken to determine the number of employees the officers supervise in the operation of their departments, where X is the number of employees overseen by each information systems officer and f is the frequency.

a) Referring to the table, how many regional offices are represented in the survey results?

Just multiply the numbers in the rows (e.g. 17,25,...) and add up all the numbers you get. — Frank, Mar 27 '14 at 14:52
This gives the total number of employees not the number of offices. — John Habert, Mar 27 '14 at 15:32

I think it's the sum of the f-column. 7 information systems officers are overseeing only 1 employee, 5 are overseeing 2 employees, etc.

So the total number of information system officers in this survey is the sum of the f-column, or 40.
