1. Is it possible to predict the mass of an Atlantic Ocean rockfish from its length? A sample of rockfish was obtained and a linear regression equation for predicting the mass of a fish (in grams) from its length was calculated. The residual plot for that model is shown below. 200 150 100 50 -50 -100 10 15 20 25 30 35 40 Length_cm Use the residual plot to determine if the linear regression model is appropriate. 2. we used a least-squares regression line to model the relationship between the height of a student (inches) and their vertical jump (inches). The standard deviation of the residuals for this model is s = 4.45 inches. Interpret this value. we used a least-squares regression line to model the relationship between pr and miles driven for 41 used Dodge Chargers. The Coefficient of Determination, r, was calculated to be 67%. Interpret the value r=0.67 for this model. Residual 3.
