. A researcher working with socioeconomic data showed a significant positive correlation between the number of local hospitals and the life expectancy of local residents (r = 0.19). Which of the following statements is appropriate? Explain why the other is not appropriate. a. 3.61% of the variance in life expectancy can be explained by the number of local hospitals b. Increasing the number of local hospitals will cause life expectancy for local residents to increase.

Step 1
In this case, r = 0.19, so R^2 = (0.19)^2. Now, let's analyze the given statements: a. 3.61% of the variance in life expectancy can be explained by the number of local hospitals. To check if this statement is appropriate, we need to calculate R^2 and see if it Show more…

B. 90% of students who receive high grades study a lot. C. 90% of the variation in GPAs can be explained by variation in number of study hours per day. D. 10% of the variation in GPAs cannot be explained by variation in number of study hours per day. E. 81% of the variation in GPAs can be explained by variation in number of study hours per day.
