The WOLF data set contains the estimated wolf population in Alaska.

The wolf population is estimated using the Mark and Recapture method.

The estimation process has been repeated for 50 times and the population estimations are captured in the WOLF data set.

​The World Wildlife Fund (WWF) is investigating whether the wolf population has drops below 6500 due to over hunting.

Perform a statistical hypothesis testing on whether the wolf population has indeed dropped to below 6500.
