How do you find the frequency in a histogram? I tried using the formula frequency density x class width = frequency but I heard something about a multiplier needed which is then multiplied by the area?

okay for the first question area=k*frequency then you need to find k so you have the mass from 1-4 and its width (4.5-0.5)=4 the frequency density =0.5 so width*fd=k*freqency (which is 10 given in the table ) 4*0.5/10 =k (0.2)
then you need to find the frequency for 5-6 where the width (6.5-4.5)=2 and fd =4 the frequency = 2*4/0.2 =40 and so on ... hope u understand

okay for the second question is the same idea width*fd=k*frequency they gave you the area and the frequency you have to find k and then use k to find the frequency to other weights
I really like histograms every question has the same idea so dont worry if you understand this ! <3 and good luck with your exam

Thanks so much! You're a life saver!! It's hard to remember and gets confusing sometimes. Thank you so much again!
