oops, ok let's do this together, 1hint: if the total frequency is 500, then the frequency up untill the blue bar = 250.

Ngl, I under estimated the difficulty of this question, keep trying I'll let you know if I find anything. Let me know too. We'll do this together.:smile: Unless someone just posts the answer.:frown:

sooo, using ur advice, i said that up to 15 is 250 and it takes up 9 class widths in terms of space and because i only want something up to 13, it takes up 7 classwidths, then i think u do, 250/ (9/7)

No, but you're trying to work out the 'Frequency not F.D.

I think what you're meant to do is count the squares for each class width and multiply it with the frequency density (aka the number of squares up) which gives the frequency of each bar. Then add the first two bars together along with half of the 12-14 bar which is why it is only an estimate. the answer is 195 i think.

hope this is right because the exams tomorrow :redface:

The total area represents 500. What proportion of the area is below 13? That proportion of 500 will give you the answer. No need for FD.
