A sample of 28 dugongs (sea cows) is collected and data on the age (in years) and length (in yards) of these dugongs is recorded. A simple linear regression model is fit to the data, treating age as the predictor variable. The intercept is estimated to be 2.0256 and the slope is estimated to be 0.0289. What of the statements below is the proper way to interpret the slope of the regression model? O A. The length of a dugong is 0.0289 yards, on average, at birth. OB. The length of a dugong increases 0.0289 yards, on average, for each year of life. O C. The length of a dugong decreases 0.0289 yards, on average, for each year of life. OD. The length of a dugong increases 2.0256 yards, on average, for each year of life.
