Explanation:
Given
So:
Required
Select all true statements
(a) & (d) Median Comparisons
Arrange the data:
--- average of 5th and 6th
Option (d) is correct because both have a median of: 2
(b) & (c) Interquartile Range Comparisons
First, calculate the lower quartile (Q1)
[Odd n]
[Even n]
This means that:
Next, calculate the upper quartile (Q3)
[Odd n]
[Even n]
This means that:
The interquartile range is
So, we have:
(b) is true because B has a greater IQR than A
(e) This is false because some spread measures (which include quartiles and the interquartile range) changed when the 10th data is included.
The upper quartile and the interquartile range of A and B are not equal
