Expert Solution
Given data,
  • The data is:

18,21, 22, 36, 32, 35, 38, 41, 43, 49, 50, 54, 57, 59, 63, 67, 71, 73, 75, 80, 82, 87, 92, 93, 95, 99, 103, 109, 111, 111, 113, 117, 119, 123, 123, 127, 129, 134, 140, 141

Step 1

Arrange the data in ascending form,

18,21, 22, 36, 32, 35, 38, 41, 43, 49, 50, 54, 57, 59, 63, 67, 71, 73, 75, 80, 82, 87, 92, 93, 95, 99, 103, 109, 111, 111, 113, 117, 119, 123, 123, 127, 129, 134, 140, 141

a) Here, number of terms is 40 (EVEN)

Now, 

Median=n2th place value+n2+1th place value2=20th place value+21th place value2=80+822=81
