The world's smallest mammal is the bumblebee bat. sch bats are roughly the same size of a bumblebee. listed below are the weights in grams from a sample of these bats. assuming that all such bats have a standard deviation of 0.3 grams, use a significance level of .05 to test the claim that these bats are from thesample data comes from a population same population with a known mean of 1.8 grams. do the bats appear to be from the same population? You may assume the that follows a normal distribution.
