Astudy 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.
(a) what is the slope of the regression line? (enter your answer rounded to four decimal places.)
(b) on average, if the depth of the dive increases by one meter, what is the increase in the diving duration? (enter your answer rounded to four decimal places.)
(c) according to the regression line, how long does a typical dive to a depth of 244 meters last? (enter your answer rounded to three decimal places.)
