the international shark attack file recorded the number of shark attacks between 1837 and 2016 for 8 different u.s. states.
what is the mean number of shark attacks over these states?

4,8, 5, 13,3,4, 1, 10

Sagot :

The mean of the data given 4, 8,5, 13, 3, 4, 1, 10 shows number of shark attacks over 8 different states is 6.

As given,

Number of different states 'n'= 8

Number of sharks attacks for 8 different states

[tex]x_{i}[/tex] = 4, 8,5, 13, 3, 4, 1, 10

Mean = [tex]\frac{\sum x_{i} }{n}[/tex]

         = (4+ 8+ 5 + 13 + 3 + 4 + 1 + 10) /8

         =48 /8

         =6

Therefore, the mean of the data given 4, 8,5, 13, 3, 4, 1, 10 shows number of shark attacks over 8 different states is 6.
