Question

the accompanying data set lists diastolic blood pressure measurements (mm hg) of females. all of the values are even numbers. construct a stemplot. identify the two values that are closest to the middle when the data are sorted in order from lowest to highest. (these values are often used to find the median.)
construct the stemplot.
6 02246668
7 022466
8 02448
9 00

Explanation:

Step1: Organize the data

First, list out all the data values: \(60,60,62,62,64,64,66,66,66,68,70,72,72,72,74,76,76,80,82,84,84,88,90,90\)

Step2: Determine the stem - and - leaf structure

The stems will be the tens digit. For example, for the value \(60\), the stem is \(6\) and the leaf is \(0\).

• Stem \(6\): Leaves \(0,0,2,2,4,4,6,6,6,8\)
• Stem \(7\): Leaves \(0,2,2,2,4,6,6\)
• Stem \(8\): Leaves \(0,2,4,4,8\)
• Stem \(9\): Leaves \(0,0\)

Answer:

Stem | Leaf
---|---
6 | 0 0 2 2 4 4 6 6 6 8
7 | 0 2 2 2 4 6 6
8 | 0 2 4 4 8
9 | 0 0
