(a)

(b)

Step-by-step explanation:

Given

Solving (a): Median and the quartiles

Start by sorting the data

The median position is:

This implies that the median is the average of the 5th and the 6th data;

So;

Split the dataset into two halves to get the quartiles

The quartiles are the middle items of each half.

So:

---- 14 is the middle item

---- 20 is the middle item

Solving (b): The interquartile range (IQR)

This is calculated as:

Solving (c): Incomplete details
