An evolutionary psychologist is comparing the grooming frequency (in bouts per day) between a species of highly social primates (FSF_SFS) and a species of solitary primates (FPF_PFP). Based on their observational data, they write:
FS≫FP F_S \gg F_P FS≫FPWhat does the symbol ≫ \gg\,≫ mean in this context?
FSF_SFS is proportional to FPF_PFP
FSF_SFS is much greater than FPF_PFP
FSF_SFS is approximately equal to FPF_PFP
FSF_SFS is statistically significantly greater than FPF_PFP
