dollars) . The coefficient of determination was found to be 98.74%.

• A)The correlation coefficient would increase because we are adding 12 additional values (one for each month) on the x-axis.
• B)The correlation coefficient would decrease because we have less data points per month as opposed to per year.
• C)The correlation coefficient would be unchanged because it is not affected by changes in units.
• D)We cannot make any conclusions about the correlation coefficient because we would need to use the new data values to calculate it.
