Confidence Interval for the population mean.
The world's smallest mammal is the bumblebee bat, also known as the Kitti's hognosed bat. Such bats are roughly the size of a large bumblebee. Listed below are weights in grams from a sample of these bats. Construct a 95 percent confidence interval approximation of their mean weight. Are the confidence interval limits very different from the limits of 1.56 and 1.87 that are found when assuming that o is known to be 0.30g?
