3.23 The following data represent the numbers of tornadoes that touched down during 1950 to 1994 in the 12 states that had the most tornadoes during this period (Storm Prediction Center, 2009). The data for these states are given in the following order: CO, FL, IA, IL, KS, LA, MO, MS, NE, OK, SD, TX. 1113 2009 1374 1137 2110 1086 1166 1039 1673 2300 1139 5490 a. Calculate the mean and median for these data. b. Identify the outlier in this data set. Drop the outlier and reealeulate the mean and median. Which of these two summary measures changes by a larger amount when you drop the outlier? Which is the better summary measure for these data, the mean or the median? Explain.
