Explanation / Answer

Within sum of squares = 244 - 132 = 112

Between degrees of freedom = 19 - 16 = 3

Between mean sum of squares = 132/3 = 44

Within mean sum of squares = 112/16 = 7

F = 44/7 = 6.286

Hence,

a) The complete table will be:

b) Population = 19 + 1 = 20

c) Option C is correct.

Source SS Df MS F Between 132 3 44 6.286 Within 112 16 7 Total 244 19
