It would help to see an example of what you are talking about but I think that if you have inequalities such as a< x< b or $\displaystyle a\le x\le b$ then the boundaries are x= a and x= b.

class intervals

20 less than equal to w less than 25

25 less than equal to w less than 30 - Nov 9th 2012, 05:44 AMHallsofIvyRe: help with class boundaries and inequalities
So the boundaries are?

Why x=a and x=b?

class boundaries 20,25 and 25,30 - Nov 13th 2012, 09:17 AManthonyeRe: help with class boundaries and inequalities
Are my class boundaries above right?

Yes.

Thank you but I thought they were class limits?

- Nov 13th 2012, 10:27 AManthonyeRe: help with class boundaries and inequalities
So are the class limits 20 and 24.9

25 and 29.5? - Nov 15th 2012, 07:34 PMvaleray12Re: help with class boundaries and inequalities
