Test 3 1. (7 points) The world's smallest mammal is the bumblebee bat. Such bats are roughly the size of a large bumblebee. A simple random sample of 31 bumblebee bats is obtained, and this sample has a standard deviation of 40 micrograms. Construct 90% confidence interval estimate of the population standard deviation.
