Hi friends,

I trust all is well with you...I'm going over some statistical questions with answers, and stumbled upon something that I just do not get, and cannot for the life of me find anything on the net that covers this ....thing...

When we have a graph, and we look at the different frequencies of each class, then the model class is obviously the range that has the higher frequency...I just do not understand why sometimes we have for example \(2 {\le x} { <6}\) and other times \(2 {< x} { \le 6}\)...how do we know where to put the "equal" sign?...

So basically, those two inequalities are completely different. The integral notation of the first is [2, 6) while the second is flipped, (2, 6]. Basically, the first one covers 2 as a solution, while the second covers 6 as a solutions. They are completely different inequalities.
