Question

the top ten medal winning nations in a tournament in a particular year are shown in the table. use the given information and calculate the mean number of gold medals for all nations round to the nearest tenth as needed

Answer 1

To calculate the mean number of gold medals for all nations, we need to add all the gold medals and then divide this number by the total number of nations. Then, we have that the total number of medals are:

T = 14 + 14 + 11 + 9 + 8 + 5 + 2 + 5 + 5 + 7 = 80

The total number of Nations is 10.

Then, the mean number of gold medals for all nations is:

`m=(80)/(10)\Rightarrow m=8`

If we round this number to the nearest tenth, the result is m = 8.

(If we round this number to the nearest ten, the result is m = 10).
