Most people think that Chicago is the windiest city in the U.S. It's not. Boston is the windiest city. The numbers below indicate the miles per hour of the winds for Boston for a 2-week period. Use the information to make a stem and leaf plot. Then find the range, median and mode. 22, 35, 27, 15, 38, 32, 22, 35, 25, 29, 22, 18, 24, 36 [For a stem and leaf plot the number 35 would have a stem of 3 and a leaf of 5] ANSWER Malen, M.
