Answer:

Mean of the sample set = 114.8  

Median of the sample set = 112

Explanation:

To calculate mean, add value of all samples and then divide with number of samples.

Mean of the sample set = (100+103+112+120+139)/5 = 114.8

To calculated median, arrange the values in ascending order then take the value which is at middle.

100, 103, 112, 120, 139

“112” is at the middle so,

Median of the sample set = 112
