Question

he data represents the heights of eruptions by a geyser.

Use the heights to construct a stemplot. Identify the two values that are closest to the middle when the data are sorted in order from lowest to highest.

Height of eruption​ (in.)
6161	3333	5050	9090
8080	5050	4040	7070
5050	6565	7171	5454
5252	6666	6262	6060
7373	7070	4747	8989

Which plot represents a stemplot of the​ data?

A.

A stemplot shows a vertical line with the numbers 3 through 9 in ascending order from top to bottom on the left side. In each of the seven rows, additional numbers appear to the right of the vertical line from left to right as follows: right of 3 is 3; right of 4 is 0 and 7; right of 5 is 0, 0, 0, 2, and 4; right of 6 is 0, 1, 2, 5, and 6; right of 7 is 0, 0, 1, and 3; right of 8 is 0 and 9; right of 9 is 0.345678930000000072412561390

B.

A stemplot shows a vertical line with the numbers 3 through 9 in ascending order from top to bottom on the left side. In each of the seven rows, additional numbers appear to the right of the vertical line from left to right as follows: right of 3 is 0, 2, and 7; right of 4 is 0, 1, and 4; right of 5 is 0, 0, and 5; right of 6 is 0, 0, and 2; right of 7 is 0, 0, and 6; right of 8 is 0, 1, and 3; right of 9 is 0 and 9.345678900000000002714526139

C.

A stemplot shows a vertical line with the numbers 3 through 9 in ascending order from top to bottom on the left side. In each of the seven rows, additional numbers appear to the right of the vertical line from left to right as follows: right of 3 is 3; right of 4 is 0, 1, 2, 4, 5 and 6; right of 5 is 0, 0, 1, and 3; right of 6 is 0, 0, and 9; right of 7 is 0, 0, 2, and 7; right of 8 is 0; right of 9 is 0.345678930000000002712456139

Identify the two values that are closest to the middle when the data are sorted in order from lowest to highest.

The values closest to the middle are

nothing

inches and

nothing

inches.

​(Type whole numbers. Use ascending​ order.)

Answer 1

The data in sorted order is,

33 40 47 50 50 50 52 54 60 61 62 65 66 70 70 71 73 80 89 90

Stem plot of the given data is,

3 | 3

4 | 07

5 | 00024

6 | 01256

7 | 0013

8 | 09

9 | 0

So, the correct option is,

A.

A stemplot shows a vertical line with the numbers 3 through 9 in ascending order from top to bottom on the left side. In each of the seven rows, additional numbers appear to the right of the vertical line from left to right as follows: right of 3 is 3; right of 4 is 0 and 7; right of 5 is 0, 0, 0, 2, and 4; right of 6 is 0, 1, 2, 5, and 6; right of 7 is 0, 0, 1, and 3; right of 8 is 0 and 9; right of 9 is 0.345678930000000072412561390

The values closest to the middle are 61 and 62.
