Question: The world’s smallest mammal is the bumblebee bat, also known as the Kitti’s hog-nosed bat. Such bats are roughly the size of a large bumblebee. Listed below are weights (in grams) from a sample of those bats. Assuming that the weights of all such bats have a standard deviation of 0.30 g, use a 0.05 significance level to test the claim that these bats are from the same population with a known mean of 1.8 g. Do the bats appear to come from the same population?
