Penguins diving. 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 the 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"

a) what is the slope of the regression line ? explain in specific language what this slope says about this penguin"s dives?

B) according to the regression line, how long does a typical dive to a depth of 200 meters last?

c)the dives varied from 40 meter to 300meter in depth . use the regression equation to determine DD for D=40 and D=300 and then plot the regression line from D =40 to D=300
