Answer:
The difference of the medians of class A and class B is between the interquartile range of either data set.
Step-by-step explanation:
Given
The attached box plots
To answer this, see attached image for how to read a box plot
With reference to the attached image of how to read the box plot;
Solving (a): The median of class A
Solving (b): IQR of class B
IQR is calculated as:
From the box plot of class B, we have:
So, we have:
Solving (c):
IQR of class A is calculated as:
From the box plot of class A, we have:
So, we have:
The difference (d) between the medians is:
From to , we have: 8, 9, 10
i.e. IQR(B), d, IQR(A)
