Create a plot with "Rate" as the y variable and "date" as the x variable. Include the equation and R2 in the plot. Create a new variable for X which is the sequence of 1 through the last "Date" value. This can be created in the column next to the "Rate" variable. Then, do a linear regression with "rate" as the Y variable and the new column of values you created for X. You do not have to plot this new data. Record the confidence interval for the slope. Is the slope significantly negative?
