Find the max and min.
96, 150
The range is R=150-96=54
Round up to 60.
Dividing by 5 would make a class width of 12.
W=60%2F5=12
Divide into 5 classes starting at 95.
095-106:XXX
107-118:XXXXX
119-130:XXXXXXX
131-142:XXXX
143-154:X
For this one, it would be one.

.
However I could have started at 92 (for example),
092-103:XXX
104-115:XXX
116-127:XXXXX
128-139:XXXXXX
140-151:XXX
For this one I would have gotten 3 in the 5th class.
