Essay

The data in the table below are the changes in the amount of space available to standing passengers at the 19 stops between 1987 and 1988. In the table below, summary information is presented for these data. ​ ​
(a)Using the raw data and summary information presented in the tables above, construct box plots to compare the changes in available space the morning and afternoon. (Reminder: Don't forget to check for outliers!)(b)The Transit System wishes to know if their efforts to improve the standing space were successful. (Remember, more space is better!) Their engineers had suggested that the changes in the system would, on average, be more successful at increasing the available space in the morning than in the afternoon. Does the data support this initial belief? What specific aspects of the plot in part (a) support your answer?
(c)Using your box plots in part (a), write a short paragraph for the New York Times describing the success the Transit System had in increasing the available space per passenger. Note any differences in success between the morning rush and the afternoon rush.
