Question

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, DD=2.69+0.0138D.is, DD=2.69+0.0138D.”  According to the regression line, how long does a typical dive to a depth of 200200 meters last?  The dives varied from 40 meters40 meters to 300 meters300 meters in depth. Use the regression equation to determine DD for D=40D=40 and D=300D=300 and then plot the regression line from D=40D=40 to D=300.to D=300. Give your answers to two decimal places.
