World’s Smallest Mammal The world’s smallest mammal is the bumblebee bat, also known as the Kitti’s hog-nosed bat (or Craseonycteris thonglongyai). Such bats are roughly the size of a large bumblebee. Listed below are weights (in grams) from a sample of these bats.

Using a 0.05 significance level, test the claim that these weights come from a population with a standard deviation equal to 0.30 g, which is the standard deviation of weights of the bumblebee bats from one region in Thailand. Do these bats appear to have weights with the same variation as the bats from that region in Thailand?
