Mean is synonymous with average. It is the sum of all the samples divided by the number of samples. The sum of the eight numbers is 469, and 469 divided by 8 equals 58.625.
The median of an even number of data is the average of the two data closest to the center of the sorted list. The sorted list is 43, 47, 49, 50, 50, 52, 52, 52, 58 & 60. The two numbers closest to the center of the list are 50 and 52, the average of which is 51.
They are: 50 52 54 56 58 and 60
32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58.
60% of 52= 60% * 52= 0.6 * 52= 31.2
Add them up. 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60
52 + (-41) + (-60) = -49
55/60 - 6/60 = 49/60
The median of an even number of data is the average of the two data closest to the center of the sorted list. The sorted list is 43, 47, 49, 50, 50, 52, 52, 52, 58 & 60. The two numbers closest to the center of the list are 50 and 52, the average of which is 51.
The composite numbers between 40 and 60 are 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, and 58

60% of 52= 60% * 52= 0.6 * 52= 31.2
Do you mean 52 minutes out of 60 minutes? If so, that would be: 52/60 which is equal to 26/30, which is equal to 13/15.
