72 CHAPTER 2 Exploring Data with Tables and Graphs 19.Cost of Giving Birth According to the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project, the typical cost of a C-section baby delivery is $4500, and the typical cost of a vaginal delivery is $2600. See the following illustration. Cost of C-Section Delivery: $4500 Cost of Vaginal Delivery: $2600 20.Incomes and Academic Degrees The accompanying graph depicts workers with various academic degrees along with their income levels. $24,544 No High School Diploma $33,852 High School Diploma $57,616 Bachelor’s Degree $80,877 Advanced Degree $ $ $ $ 21.Expanded Stemplots A stemplot can be condensed by combining adjacent rows. We could use a stem of “6–7” instead of separate stems of 6 and 7. Every row in the condensed stemplot should include an asterisk to separate digits associated with the different stem values. A stemplot can be expanded by subdividing rows into those with leaves having digits 0 through 4 and those with leaves having digits 5 through 9. Using the body temperatures from 12 AM on Day 2 listed in Data Set 5 “Body Temperatures” in Appendix B, we see that the first three rows of an expanded stemplot have stems of 96 (for leaves between 5 and 9 inclusive), 97 (for leaves between 0 and 4 inclusive), and 97 (for leaves between 5 and 9 inclusive). Construct the complete expanded stemplot for the body temperatures from 12 AM on Day 2 listed in Data Set 5 “Body Temperatures” in Appendix B. 2-3 Beyond the Basics
