Answer: The estimated total number of fur seal pups in Rookery A is 1100.
Step-by-step explanation:
Let the total number of fur seal pups in Rookery A be 'x'.
Number of fur seal pup population in Rookery A = 6048
if the number of sample pups = 1200
Number of fur seal pups among them = 217
So, Using this proportion, we get that
[tex]\dfrac{x}{6048}=\dfrac{217}{1200}\\\\x=\dfrac{6048\times 217}{1200}\\\\x=1093.68[/tex]
So, the estimated total number of fur seal pups in Rookery A is 1100.
