Explanation:

Step1: Sort the data

32, 40, 42, 50, 50, 50, 53, 50, 60, 63, 69, 60, 73, 70, 70, 87, 80, 90
Sorted: 32, 40, 42, 50, 50, 50, 50, 53, 60, 60, 63, 69, 70, 70, 73, 80, 87, 90

Step2: Find the middle - position

There are \(n = 18\) data points. The middle - positions for an even - numbered data set are \(\frac{n}{2}=9\) and \(\frac{n}{2}+1 = 10\)

Step3: Identify the middle values

The 9th value is 60 and the 10th value is 60

Answer:

60, 60
