Bagian a

[tex] = \frac{(11 + 12 + 12 + 12 + 12 + 13 + 14)}{7} [/tex]

[tex] = \frac{86}{7} [/tex]

[tex] = 12.29[/tex]

Bagian b

[tex] \\ = \frac{(108 + 103 + 98 + 105 + 85 + 112 + 119 + 82 + 94 + 115 + 126)}{11} [/tex]

[tex] = \frac{1147}{11} [/tex]

[tex] = 104.27[/tex]

Bagian c

[tex] = \frac{40 + 50 + 55 + 60 + 8 + 37 + 50}{7} [/tex]

[tex] = \frac{300}{7} [/tex]

[tex] = 42.86[/tex]

Bagian d

[tex] = \frac{12 + 16 + 0 + 8 + 31 + 28 + 17}{7} [/tex]

[tex] = \frac{112}{7} [/tex]

[tex] = 16[/tex]

Nomer 2

[tex] \rm mean = \frac{jumlah\: data}{banyak \: data} [/tex]

[tex]6.5 = \rm \frac{x}{12} [/tex]

[tex] \rm x = 6.5 \times 12[/tex]

[tex] \rm x = 78[/tex]

Jadi, jumlah seluruh data tersebut adalah 78
