The mean of n = 72 observations is
You can use this information to find i = 1 72 X i and from there to find i = 1 73 X i and from there X ¯ 73 ..
To find the median of all 73 observations you need to know observation number 74 / 2 = 37 of the sorted data. I think you may be expected to assume all of the X i are integers. What does the given information tell you about the middle two observations when the original 36 are sorted?
Finally, what is the minimum number of the original observations that must have had value 54?
