Hey there, welcome to numerade.
00:03
We are given a frequency distribution table here, looking at the weights of sample of visitors at a health clinic.
00:13
So we're asked to find the class width.
00:18
So what we know about the class width here is basically equal to the lower class limit of b minus lower class limit limit of the class before proceeding.
00:40
But the class width is going to be the same in ways for comparing any two classes.
00:48
So we can just do our first one here in which we have 110 for our second class for the lower class of our second class minus 100 for our lower class of our first class given us a class width of 10.
01:08
All right.
01:10
So now we are are asked to find the class boundaries.
01:17
Class boundaries is basically taken the, just find the value itself like the adding subtracted.
01:36
So we're going to start with our second class here, which is 110.
01:41
We take 110 minus the upper class of our first class, which is 109 divided by 2...
