A modified box-and-whisker plot is a box-and-whisker plot that uses symbols to identify outliers. The horizontal line of amodified box-and-whisker plot extends as far as the minimum data entry that is not an outlier and the maximum data entry that is notan outlier.

Citi Bike is a privately owned public bicycle sharing system in New York City that has become increasingly more popular in the past few years. Citi Bike is designed to provide an alternative version of public transportation. Trips taken on daily or 3-day passes are limited to 30 minutes before extra fees are charged. The following data indicate the trip times in minutes for a single Citi Bike in a daily period. (a) Create a stem-and-leaf plot for the data.
