Question

Find the mean of 22 30 38 40 45 45 46 46 48 49

Answer 1

To find mean, add all the numbers together, and divide by the amount of numbers there is.

(22 + 30 + 38 + 40 + 45 + 45 + 46 + 46 + 48 + 49) = 409

The total is 409, and there are 10 numbers.

Divide 409 with 10

409/10 = 40.9

40.9 is your answer

hope this helps

Answer 2

Hi ,




Observations are : 22 , 30 , 38 , 40 , 45 , 45 , 46 , 46 , 48 , 49.




Mean = Sum of observations/ Number of observations.




=> ( 22 + 30 + 38 + 40 + 45 + 45 + 46 + 46 + 48 + 49 ) / 10



=> 409/10




=> 40.9
