To count whale populations, the "capture" is done by means of a photograph, and the "tagging" is done by identifying each each captured whale through their unique individual pigmentation and markings.  To estimate the population of gray whales in a region of the Pacific between Northern California and Southeast Alaska, 121 gray whales were "captured" and "tagged" in 2007.  In 2008, 172 whales were "recaptured".  Of these, 76 had been "tagged" in the 2007 survey.  Based on these figures, estimate the population of gray whales in the region. There were approximately Answer gray whales in the region.

1) The rabies vaccine for dogs can save your dog's life. If your dog bites another animal or is on the receiving end of a bite, the vaccine can protect them from a dangerous and potentially fatal illness. Furthermore, in most places, the rabies vaccine for dogs is legally required. The NYC Department of Health wants to know if LESS than 95% of the dogs in the city have been vaccinated with their rabies vaccine.  158,045 of the 165,000 dogs examined had their rabies shots.  Risk no more than 5% Type I error.  What are the hypotheses?
