The accompanying data set consists of observations on shower-flow rate (L/min) for a sample of n = 129 houses in Perth, Australia (“An Application of Bayes Methodology to the Analysis of Diary Records in a Water Use Study,” J. Amer. Stat. Assoc., ?1987: 705–711): a. ? onstruct a stem-and-leaf display of the data. b. ? hat is a typical, or representative, flow rate? c. ?Does the display appear to be highly concentrated or spread out? d. ?Does the distribution of values appear to be reasonably symmetric? If not, how would you describe the departure from symmetry? e. ?Would you describe any observation as being far from the rest of the data (an outlier)?

Solution : Step 1 : The given data set consist of consists of observations on shower-flow rate (L/min) for a sample of n = 129 houses in Perth, Australia . we have make a stem leaf diagram based on the data and want to interpret the diagram.
