Data is gathered to examine the relationship between the length of the left middle finger (measured in centimeters) and height (measured in inches) for a random sample of adults. This data is presented in the accompanying scatterplot. To predict height based on left middle finger length, the following regression equation is constructed: Predicted height = 24.43 + 3.54 (finger length). The correlation between height and left middle finger length is r = 0.76. Based on this information, which one of the following statements is correct? (Note that if the image below is not showing up for you, you can download it here Download here) Scatterplot of finger length versus height Group of answer choices As left middle finger length increases by 1 centimeter, we predict height to increase by 24.43 inches. It would be extrapolation to use the regression equation to predict the height of an adult with a left middle finger that is 12.9 cm long. An adult with a left middle finger length of 11.5 centimeters is predicted to have a height of 63.24 inches. As height increases by 1 inch, we predict length of the left middle finger to increase by 3.54 centimeters. Approximately 58% of the
