Task 3 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 years after marking) on the x-axis. mass 5000 5200 4800 4000 4200 0.0 8 Residuals: Min O O time 0.5 1.0 time A regression analysis is performed, where the printout becomes (three of the numbers in the printout have been replaced by respectively "AAA", "BBB" and "CCC"): Call: 1m (formula = mass time, data gentoo) 1Q Median 3Q -722.11 -171.94 16.31 194.81 O > n <- length (mass) > n [1] 58 > mean (time) [1] 1.353312 2.0 Max 528.82 Coefficients: Estimate Std.
