Question

The textbook wants me to graph something using a feature on mygraphing calculator...hwo do I do this? Use the data to find linear models for women's and men'stimes. Year:    1968   1972   1976      1980 1984  1988   1992    1996      2000 Men:   43.86   44.66   44.26   44.60   44.27   43.87   43.50   43.49   43.84 Women:52.03   51.08   49.29   48.88   48.83   48.65   48.83   48.25   49.11 X=number of years since 1968 y=winning times It says to use the LinRegfeature on thecalculator, howeverm when I type anything in, it says dimerror...what's that mean? Please give a Step=by-step process for how to solve this on aTI-84 graphing calculator!!! The textbook wants me to graph something using a feature on mygraphing calculator...hwo do I do this?

Explanation / Answer

You first need to put all the years and men times and womentimes into 3 columns under STAT - EDIT. Then, when you're done. Go back into STAT -CALC to LINREG. you need to tell the calculator which TWO columns touse. First use L1 and L2   (years and men) Enter You will get an answer as a x + b . This is theregression equation for those two variables Repeat using L1 and L3 to find the regression equationfor years and women.
