Arranging the given data in ascending order:
33, 35, 41, 46, 55, 58, 64, 77, 87, 90, 92
Number of terms = 11 (odd)
Hence, the median of the data is 58.
Now, In the above data, if 41 and 55 are replaced by 61 and 75 respectively.
Then, new data in ascending order is:
33, 35, 46, 58, 61, 64, 75, 77, 87, 90, 92
Number of terms = 11 (odd)
Hence, the new median of the data is 64.
