In this assignment, we will look at data for the weight of adult female penguins of the species Gentoo
which lives around Antarctica. Researchers have collected data for a selection of penguins to learn
more about them other about the development in the weight of these penguins over time. A total of
58 penguins of the same age were marked and then these were subsequently weighed at various
times. The figure below shows weight (mass, measured in grams) on the y-axis and time (hours, in
