Simple linear regression

Create a scatter-plot in Excel with "Annual Amount Spent on Organic Food" on the y (vertical) axis and "Age" on the x (horizontal) axis. Insert a trend-line. What does the trend-line indicate about the relationship between these two variables? Calculate the correlation coefficient for these two variables using the =CORRELATION° formula in Excel. Interpret the correlation coefficient. Does the correlation coefficient agree with the slope of the best fit line? Explain. Add the equation for the best fit line on the chart. Does this equation match the linear regression equation from the Case for this module? Explain.
