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.

Answer

Explanation:

Step1: Sort the data

62, 64, 66, 66, 66, 68, 68, 70, 70, 70, 70, 72, 72, 74, 74, 74, 74, 76, 76, 76, 78, 80, 80, 84, 88, 94

Step2: Construct the stemplot

The tens - digit will be the stem and the units - digit will be the leaf.

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

Step3: Find the middle values

There are (n = 26) data points. The position of the middle values for an even - numbered data set is (\frac{n}{2}=13) and (\frac{n}{2}+1 = 14). The 13th value is 74 and the 14th value is 74.

Answer:

Stemplot:

Stem Leaf
6 2 4 6 6 6 8 8
7 0 0 0 0 2 2 4 4 4 4 6 6 6 8
8 0 0 4 8
9 4
The two values closest to the middle are 74, 74.
