Question 5

A marine biologist is monitoring the dive durations (in minutes) of two groups of gentoo penguins under different foraging conditions:

  • Group X: Penguins foraging in a Marine Protected Area (MPA) with high prey density.
  • Group Y: Penguins foraging in an Open-Access fishing Zone (OAF) with depleted prey density.

Table 1: Dive duration statistics (in minutes)

Group X (Marine Protected Area)Group Y (Open-Access Zone)
Median dive duration (minutes)4.22.5
Range (minutes)1.13.8

What do the median and range values presented in Table 1 suggest about the dive durations of the penguins in each group? Justify your answer in context.
