Construct a stem-and-leaf plot and find the quartiles number of blocked intrusion.

Answer 1

Answer:

• quartiles: 43, 56
• median: 50

Step-by-step explanation:

A stem-and-leaf plot is a kind of histogram in which the most significant digit of a data value is taken to be the "stem", and the "leaves" are a list of the least-significant digits of the data values. It is convenient to list the leaves in increasing order, to facilitate determining the quartiles in the data.

__

The 14 data set values can be represented by the plot below. Here, we have elected to use parentheses ( ) to identify the 1st and 3rd quartile values, and a slash / to signify the location of the median.

__

stem | leaves

3 | 7 8

4 | 3 (3) 7 9

5 | 0 / 0 3 4 (6) 9 9

6 | 0

_____

The first and third quartiles are 43 and 56, respectively. The median is 50.
