Research was conducted on the amount of oxygen runners could utilize during training, known as their VO2VO2 max, and their finishing times for a 5K race to see if there was a significant relationship between these variables. The results for 8 runners were compiled and placed in the following table. VO2VO2 Max (ml/kg/min) 5K Finishing Time (min) 22.39 34.5 23.77 32.65 24.02 35.55 39.01 26.38 24.78 32.09 22.12 31.92 37.15 26.48 44.61 23.01 Calculate the correlation coefficient. Round to three decimals r = Find the equation of the regression line. Round each value to two decimals Predict the time in the 5K for a runner whose VO2VO2 max is 29.94 ml/kg/min. Round your answer to two decimals
