I need help on a question on a Statistics worksheet I was given. The question is:
A histogram uses a bar of width 2 cm and height 5 cm to represent a frequency of 30. A second bar is 4 cm wide. What height would it need to be to represent a frequency of 50?
Can someone please tell me how to work this out? I don't think it's as simple as proportion and doesn't
FD=F/CW have something to do with this?
