Hi,

In case you are still interested:

Stem and Leaf plot
3 1
4
5
6 7 6 2
7 5 0
8 3 2 0 5 7 9
9 1 9 4 6 2 8
10 0

A: What are the 7 lowest scores ?
You have the stem digits 3,4,5,..., 10
1 next to the 3 is a trailing digit or a leaf.
It makes 31
However there are no leaf digits for 4 and 5. Do you assume 0?
If so, then the 7 lowest scores would be 31,40,50,67,66,62,70

B : How many students scored at lest 92 on the math quiz ?
So, again we look at stem 9 and leaf 2
We have 92, 94,96,98,99,100

C : What is the range of the data set ? Data range from 31 to 100

I hope it is clear and correct.

Could anybody please also correct my grammar mistakes?
