For this exercise, we are asked to find the class boundaries midpoint and width for this class.
00:08
Now, in order to find the boundaries, we actually have to know the limits of the classes that are below and above this class.
00:16
So this class is 46 to 52.
00:21
Now, you must have been given the other classes in the question somewhere else, which is not on the web page.
00:28
But i'm going to make an assumption that the next higher class is 53 to something.
00:37
And that the next lower class is something to 45.
00:45
Now if these numbers are different from what's given in your question, then you'll just have to modify the solution accordingly.
00:54
To find the lower boundary, or the lower class boundary, this is the midpoint of the lower class limit for this class, and the upper class limit of the next lower class.
01:17
So this is the average of 45 and 45.
01:32
And the upper class boundary is the midpoint of the upper class limit and the lower class limit of the next higher class...
