Question: 14.Extra credit (5 points): A researcher makes the following statement: "My research shows that 30.25% of the variability in severity of arthritis in elderly adults (as measured by a continuous scale) is explainable by knowing the number of hours per week these adults spent on strength training in early adulthood." How did the researcher arrive at this number? Is the direction of the relationship between arthritis severity and hours of exercise per week apparent from this statement alone?
