Textbook Question

Chapter 2.3, Problem 21BB

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 3 “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 3 “Body Temperatures” in Appendix B.
