The smallest mammal in the world. The smallest mammal in otherworld is the bumblebee bat, also known as a pig-nosed bat. These animals barely reach the size of a large bumblebee. The weights (engrams) of a sample of these bats are included below. Use significance level of 0.05 to test the claim that these weights come from a standard deviation of 0.30 grams, which is the standard deviation of the weights of bumblebee bats from a region IN Thailand. Do these bats appear to have weights with the same variation as bats from that region in Thailand?
