MEI S1 Jun 07 Q2 - Freq Table HELP

:confused:

Part two says work out the sum, but I don't know where they got their values from.

I understand how they worked out the customer values, 800, 480, etc but not 10 and the other smaller figures.

Could someone help point out the obvious?

OP really should post the question but....

They got the numbers from the histogram using the key.

The other values you are referring to are mid interval values....probably. Can't be sure as you were not clear and I don't have the MS.

Thats it, it's half way. I'll remember the key was 'estimate' hence half way. Cheers!
