An exercise specialist was interested in predicting the run time from running plus rate, resting pulse rate and max pulse rate. He measured these values for 31 individuals and found the regression equation below. yhat = 4.85 + 0.08runpulse + 0.07respulse - 0.06maxpulse One of the participants had a runtime of 12, run pulse of 172, fest pulse of 40 and a max pulse of 172. What is the residual? Round your answer to one decimal point. Include the negative sign if appropriate
