4. The world’s smallest mammal is the bumblebee bat, also known as the Kitti’s hog-nosed bat (or Craseonycteris thonglongyai as it is affectionately called). Such bats are roughly the size of a large bumblebee. Listed below are the weights (in grams) from a sample of these bats. Construct and interpret a 95% confidence interval of the “standard deviation” of weights of all such bats.

bats=c(1.7,1.6,1.5,2,2.3,1.6,1.6,1.8,1.5,1.7,2.2,1.4,1.6,1.6,1.6
