Question

construct a stemplot showing life expectancies of males in eight nations. round to the nearest year and use split stems. then write a brief interpretation of the stemplot. click the icon to view the male life expectancy data. complete the stem - and - leaf plot below. life expectancy of males (type whole numbers. use ascending order.) data table nation a b c d e f g h male 74.2 57.5 60.7 73.2 69.7 65.6 64.7 53.4

Explanation:

Step1: Round the data to whole - numbers

$53.4\approx53$, $64.7\approx65$, $65.6\approx66$, $69.7\approx70$, $73.2\approx73$, $60.7\approx61$, $57.5\approx58$, $74.2\approx74$

Step2: Organize data for stem - and - leaf plot

The stems will be the tens digits and the leaves will be the units digits. Using split stems (e.g., 5 will have two stems: 5 | 0 - 4 and 5 | 5 - 9).
The ordered data in ascending order for the stem - and - leaf plot: 53, 58, 61, 65, 66, 70, 73, 74
The stem - and - leaf plot:
5 | 3 8
6 | 1 5 6
7 | 0 3 4

Step3: Interpretation

The stem - and - leaf plot shows that the life expectancies of males in these eight nations range from 53 to 74 years. The data seems to be somewhat spread out, with no strong clustering in any particular range. There is a relatively even distribution across the different tens - digit intervals.

Answer:

Stem - and - leaf plot:
5 | 3 8
6 | 1 5 6
7 | 0 3 4
Interpretation: The life expectancies of males in the eight nations range from 53 to 74 years with a relatively even spread across different tens - digit intervals.
