    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

    Here are the answers:

    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?
