Answer 1

Answer:

Household size (x)                 Frequency (f)                    fx

           1                                           3                            1 × 3 = 3

           2                                          4                            2 × 4 = 8

           3                                          6                            3 × 6 = 18

           4                                          7                            4 × 7 = 28

           5                                          5                            5 × 5 = 25

Total of fx (Σfx) = 3 + 8 + 18 + 28 + 25 = 82

Total frequency (Σf) = 3 + 4 + 6 + 7 + 5 = 25

Mean = Σfx ÷ Σf = 82 ÷ 25 = 3.28
