    Hi;
    I need to make a histogram on a ti-83 but don't know where to start.


    The data I have is as follows.

    class boundaries frequency
    99.5-104.5 2
    104.5-109.5 8
    109.5-114.5 18
    114.5-119.5 13
    119.5-124.5 7
    124.5-129.5 1
    129.5-134.5 1
    Thanks.

    You can't enter intervals, you will need to enter the midpoint of each interval instead.
