For all but the shallowest dives, there is a linear relationship that is different for different penguins. The study report gives a scatterplot for one penguin titled The relation of dive duration (DD) to depth (D). Dive duration DD is measured in minutes and depth D is in meters. The report then says, "The regression equation for this bird is: DD 2.19+0.0116 D. Problem 2 Problem 3 Problem 4 Problem 5 (a) What is the slope of the regression line?
