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:
The starting weight of the radioactive isotope = 96 grams
Weight after one hour is half of the starting weight. So the weight of the radioactive isotope after 1 hour = 48 grams
After 2 hours the weight is half as compared to the weight after previous hour. So weight after 2 hours = 24 grams.
This means, after every hour the weight is being halved. The half life of radioactive isotope is one hour.
Since after every hour, the weight is being halved, the weight of the isotope can be modeled by an exponential equation.
So,
Initial Weight = W₁ = 96
Change factor = 1/2 = 0.5
The general equation of the sequence will be:
Here t represents the number of hours. Using various values of t we can find the weight of the radioactive isotope at that time.
We can plot the sequence using the above equation. The graph is attached below.
