Determine the correlation coefficient and interpret it. (Include the negative sign, as appropriate, directly before the value. Enter your "r" answer to 4 decimal places. Enter your first "r2" answer as a proportion (between 0 and 1) and to 2 decimal places. Then enter the next answer as the percentage equivalent to the nearest whole number percent. Omit the "%" sign in your response.)
