2. Lower quartile is B*7.5*
3. Upper quartile is D*16*
4. Interquartile range is C*11*
5. Interquartile range is D*9*
I got a 45.5% :(
To find the upper quartile, you need to first arrange the numbers in ascending order.
The given list of numbers: 27, 5, 11, 13, 10, 8, 14, 18, 7
Arrange the numbers in ascending order: 5, 7, 8, 10, 11, 13, 14, 18, 27
The upper quartile divides the data into quarters and represents the value that separates the top 25% of the data. To find the upper quartile, you need to find the median of the upper half of the data set.
In this case, the upper half of the data set is: 11, 13, 14, 18, 27
Now, find the median of this upper half:
Median = (14 + 18) / 2
Median = 32 / 2
Median = 16
So, the upper quartile is 16.
Therefore, the correct answer is D. 16.
