Explanation / Answer

Formula for mean:

Mean = Sum of observations / n

Hence,

a) Mean for data set I = (5 + 7 + 7 + 9 + 9)/5 = 37/5 = 7.4

Mean for data set II = (9 + 9 + 9 + 9 + 9)/5 = 45/5 = 9

Mean for data set III = (5 + 5 + 5 + 5 + 5)/5 = 25/5 = 5

Mean for data set IV = (5 + 6 + 6 + 7 + 10)/5 = 34/5 = 6.8
