You have 14 values. The median is the average of value 7 and value 8.
Median=36.5

Your average is 72. CORRECT
You have 30 values. The median is the average of value 15 and value 16.
Median=70
You calculated the standard deviation using the definition for a sample of a population but you should have used the definition of standard deviation of the entire population

Your average is 4.05. CORRECT
You have 60 values. The median is the average of value 30 and value 31.
Median=4
You calculated the standard deviation using the definition for a sample of a population which is the correct definition based on the problem setup. But you have to round up to get to 2 decimal places.
