Median Recovery Time Calculation

A researcher collected data from a sample of 100 patients to evaluate the effectiveness of a new medication. The results of their recovery times (in days) are summarized below:

Data: 12, 15, 18, 21, 22, 24, 22, 35, 13, 28, 30, 29, 34, 26, 25, 20, 19, 27, 40, 15, 23, 31, 18, 22, 19, 25, 36, 24, 12, 15, 38, 32, 30, 22, 24, 31, 28, 18, 39, 30, 27, 14, 35, 26, 32, 12, 22, 28, 30, 19, 21, 22, 15, 34, 25, 27, 33, 28, 24, 18, 18, 36, 13, 40, 31, 29, 30, 25, 28, 22, 22, 19, 30, 28, 25, 20, 21, 37, 15, 12, 11, 30, 24, 25, 19, 30, 21, 19, 40, 38, 15, 12, 15, 45, 20, 18, 22, 17, 21, 22, 24, 27, 28, 12

Calculate the median recovery time for the patients.
