Consider the 25th percentile SAT scores for the data given in Exercise 1.7. If you wanted to construct a graphical display that would spotlight any outliers with small values, what display would you use? Construct that display for these data. Are there any outliers? Explain.
The U.S. Consumer Product Safety Commission reported in an October 23, 2002 memorandum (http://www.cpsc.gov/library/toydth01.pdf) that for 2001, 79% (202,500) of the estimated number of toy-related injuries were sustained by children under the age of 15; 30% (77,100) were under the age of 5.
(a) What were the number of toy-related injuries for children at least 15 years old and the total number of injuries?
(b) What graphical display would you suggest be used to show breakdown of toy related injuries among these age groups?
