Answer:
The lower quartile is thousand dollars.
The median quartile is thousand dollars.
The upper quartile is thousand dollars.
Step-by-step explanation:
The lower quartile is the median value of the lower half of a data set at the 25th percentile of a distribution.
The median quartile is the median value of a data set at the 50th percentile of a distribution.
The upper quartile is the median value of the upper half of a data set at the 75th percentile of a distribution.
To locate each quartile in a data set, we follow four steps:
Step 1: Put the numbers in order: 23, 25, 33, 34, 39, 39, 44, 45, 48, 55
Step 2: The median is given by where n is all scores in the data set.
Because n = 10, the median position is
The median is the average of the fifth and sixth positioned scores
Step 3: Compute where n is all scores below
.
For scores below , use only 23, 25, 33, 34, 39.
Because n = 5, the median position is
The median is the third positioned score:
Step 4: Compute where n is all scores above
.
For scores above , use only 39, 44, 45, 48, 55
Because n = 5, the median position is
The median is the third positioned score:
Answer:
See below for the matrix
D = 100
Step-by-step explanation:
3 2 1
D = -1 -2 4 = 3(-2)(-3) + 2(4)(1) + 1(-1)(-6)
1 -6 -3
- 1(-2)(1) - 3(4)(-6) - 2(-1)(-3)
= 18 + 8 + 6 + 2 + 72 - 6
= 100
