a) Using the data in the file (i.e., the values of Y and values
of X), create a scatter plot with the variable Y plotted vertically
and the variable X plotted horizontally. You are to add a
trendline, the equation of the line and R2 to this scatter plot.
You do not need to add a title to this plot.
