Solution

a) Mean of Five = (108+100+99+103+93)/5 = 100.6
b) Mean of Twelve = 108+100+99+103++93+106+109+117+101+106+112+95/12= 104.089
c) Mean of Thirty = (108+100+99+103++93+106+109+117+101+106+112+95+118+111+101+94+94+117+96+96+115+94+91+115+91+111+100+114+97+116)/30=104
d) Median of 5 = Middle MOst one = 100
e) Median of 12 = 104.5
