    Portfolio Piece Question (very, very urgent)

    Ok, I was assigned the following question as a portfolio piece a few days back. Unfortunatly the due date was moved up an entire week due to some things my teacher has going on. Any help is greatly appreciated!

    The question :

    Based on the following model graph, who would you say is a safer driver : a 16 year old driver or a 70 year old driver? Explain.

    Driver's Age , Accidents per million miles driven
    25 , 430
    30 , 340
    40 , 220
    45 , 190
    55 , 190
    60 , 220

    (end question) EDIT : The chart came out strange, the two columns are supposed to be Age and Accidents with the respective data under each.

    I'm fairly certain that I need to find the equation used for this data, enter it into my graphing calc (TI-83), and compare the two ages. Does anyone have any ideas how I would go about doing this? Thanks!

    I'm thinking the QuadReg function on my TI-83 has something to do with finding the correct formula...?
