Document Summary
At the eurelian space agency a test was performed to determine the usefulness of a new training system. Half of the subjects received the training and half did not. They were then all tested, and each subject was given a score from 0 to 70. a) One of the following data sets is a stem-and-leaf diagram of the scores. That suggests that there will end up being a data set that is bimodal: one group with typically lower scores and a second group with typically higher scores. The data set on the left is bimodal, so is more likely to h the result. b) Use tukey"s method to find the five-point summary of data set ii). Since no data number is either greater than the upper inner fence or less than the lower inner fence, there are no tukey-style outliers. Use the interpolation method to find the 60th percentile of data set ii).
