A study of king penguins looked for a relationship between how deep the penguins dive to seek food and how long they stay underwater. 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)." Duration DD is measured in minutes and depth $$D$$ is in meters. The report then says, " The regression equation for this bird is: $$\mathrm{DD}=2.62+0.0115 \mathrm{D}$$ (a) What is the slope of the regression line?. ANSWER minutes per meter. (b) According to the regression line, how long does a typical dive to a depth of 225 meters last? ANSWER minutes.
