The scatterplot shows Olympic gold medal performances in the long jump from 1900 to 1988. The long jump is measured in meters. The regression equation is predicted long jump - 7.24 + 0.014 * year since 1900. 9.0- 8.8- 8.6- 8.4 8.2 Long jump 8.0 7.8 7.6 7.4 7.2 O 7.0 20 40 60 80 100 120 Year since 1900 What does the slope of the regression line tell us? Each year the winning Ohmpic long jump performance is expected to increase 7.24 meters. Each year the winning Olympic long jump performance is expected to increase 0.014 meters. Each time the Olympics are held (generally every four years), the long jump gold medal winner will definitely achieve a 0.014 meter increase over the previous gold medal winner. Each time the Olympics are held (generally every four years), there is a predicted 1.4% increase in long jump performance
