Expanded and Condensed Stemplots

a. A stemplot can be expanded by subdividing rows into those with leaves having digits of 0 through 4 and those with leaves having digits 5 through 9. Using the body temperatures from 12 am on Day 2 listed in 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 of Appendix B.

b. A stemplot can be condensedhy combining adjacent rows. Using the LDL cholesterol measurements from males we obtain the first two rows of the condensed stemplot as shown below. Note that we insert an asterisk to separate digits in the leaves associated with the numbers in each stem. Every row in the condensed plot must include exactly one asterisk so that the shape of the condensed stemplot is not distorted. Complete the condensed stemplot. What is an advantage of using a condensed stemplot instead of one that is not condensed?

Answer:

Step1 of 2:

We have A stemplot can be expanded by subdividing rows into those with leaves having digits of 0 through 4 and those with leaves having digits 5 through 9. Using the body temperatures from 12 am on Day 2 listed in 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).
