A. Mean: 11.73 Median: 5.05
To find the mean (average) of a set of numbers, just add all of the numbers, and then divide your sum by the amount of numbers there are. So in this case, your sum would be 117.3. If you divide that by 10 your answer will be 11.73, so that's the mean.
To find the median of a set of data, put the numbers in order from least to greatest and just find the middle number. If the set of data contains an odd amount of numbers, than finding the median is very easy. However, if it contains an even amount of numbers, than you must take the two numbers in the middle, which in this case would be 4.7 and 5.4, and fine the middle number of those two numbers.
B. I'm not quite sure about this one, but because the median is described as the "middle" number, I'm guessing that the answer would be the median of this set of data (5.05).
