Part III. Magazine Ads
The following data was collected in past years to try to determine how the number of
Magazine ads affect candle sales. Plot the points and use technology to find the linear
regression line that best fits the data. Graph the line of best fit along with the data
points. You may either include a graph produced with technology or carefully graph the
points and the line of best fit by hand below.
