anonymous · Answer

would the mean of the data be  11.43 or 11.4

liv1234 · Answer

To find the mean you add up all of the numbers and then you divide the sum of the numbers by the amount of numbers you have.

liv1234 · Answer

$$2+ 4+ 6+ 6+ 8+ 10+ 11+12+14+ 16+ 17 +18 +18+ 18=160$$

liv1234 · Answer

$$160/14=11.42$$

anonymous · Answer

liv1234 · Answer

Ohh okay, so your answer to the mean would be 11.42.

anonymous · Answer

so now I would have to subtract or add the numbers from 11.42

liv1234 · Answer
