The subject of this question is Mathematics and it is asking to calculate the mean and median of the number of months patients wait on a transplant list before getting surgery.
Step-by-step explanation:
The subject of this question is Mathematics. The question asks to calculate the mean and median of the number of months patients typically wait on a transplant list before getting surgery.
Mean: The mean is calculated by summing up all the values and dividing by the total number of values. In this case, you would sum up the number of months patients wait and divide by the total number of patients.
Median: The median is the middle value when the data is arranged in ascending or descending order. If there is an odd number of data points, the middle value is taken as the median. If there is an even number of data points, the average of the two middle values is taken as the median.
