Read directly from the chart:
Intercept = 6,223
Slope = 103.27
R2 = 0.6581
Use Excel to predict the number of minutes spent by a 37-year old shopper. Enter = followed by the regression formula. Enter the intercept and slope into the formula by clicking on the cells in the regression output with the results.
*I used (103.27*37) +37 = 3858-Is this correct?
* Is it appropriate to use this data to predict the amount of time that a 68-year-old will be on the Internet? Yes (is this correct?)
If yes, what is the amount of time, if no, why?
I used (103.27*68)+68-Is this correct?
